    darwin: clean up old code
    
    For some time only one type of completion message has been in use in the darwin
    backend. The commit cleans up this code. This commit also removes some code
    that has never done anything useful. If a pipe has an error it probably means
    the device was closed so there is nothing to do.

    darwin: fix memory leaks in the darwin backend.
    
    There were two memory leaks in the darwin backend:
     - A CFString allocated by IORegistryEntryCreateCFProperty in darwin_get_interface()
       was not released.
     - The runloop is retained by darwin_open() but was not release by darwin_close().

    core: release the context device list when the context is deleted.
    
    This commit fixes a memory leak in the context list patch. Devices need
    to be unref'd when the context is deleted. This can happen if either 1)
    the backend init fails, or 2) the context is destroyed by libusb_exit().

    Add APIs for parsing the Endpoint Companion and BOS descriptors.
    
    Nathan: Modified the original patch to fit the interface now already
    provided by the FreeBSD implementation of libusb 1.0 and fit with
    the rest of libusb.h.
    
    Some discussion: The FreeBSD API is not optimal. Further discussion
    is needed to determine how to update the API without breaking code
    that used the existing API. This discussion should probably involve
    the FreeBSD developers and could be handled in a 1.0.x release.
    
    An example has been added to show how to use the new API.
    
    Fixes #110

    Linux: Avoid unnecessary splitting of bulk transfers
    
    * With the latest kernels it is no longer needed to always split large bulk
      transfers into multiple urbs. This patch takes advantage of this by not
      splitting when not necessary. Note that the non-split code path is in essence
      using the old split code path with an urb count which is always 1.
    * This leads to more sane handling of large transfers with recent kernels,
      although our splitting code is well tested, not splitting at all still is
      a lot better :)
    * When used with a recent kernel, this also fixes the problems, on XHCI attached
      devices, when a large bulk-in transfer ends with a short read in an urb other
      then the last urb.
    * For more on this see: http://marc.info/?l=linux-usb&m=133797554910355

    Linux: Add support for the new get_capabilities ioctl
    
    * There were a few (new) usbdevfs capabilities which libusbx could not
      discover in any other way then checking the kernel version.
    * However, this presents the following problems:
      1) It is just not very pretty
      2) Given the tendency of enterprise distros to backport stuff it is not
         reliable
      3) Some of these features turn out to not work with certain host controllers,
         making depending on them based on the kernel version not a good idea
    * Therefore a new USBDEVFS_GET_CAPABILITIES ioctl has been added to the kernel
      to offer a better way to find out a device's capabilities (technically
      the capabilities of the host controller to which the device is attached,
      but that does not matter).

    darwin/libusb_reset: reenumerate device if the device descriptor or any
    configuration descriptor has changed
    
    Some background: the Linux kernel causes a device to be reenumeration when
    reset if the device's descriptors have changed. Darwin does not provide
    this feature but instead provides a call to force the reenumeration of
    a device. This behavior is required to support the firmware update
    protocol used by some devices.
    
    This patch updates darwin_reset to check if either the device or
    configuration descriptors have changed. If they have darwin_reset will
    ask the OS to reenumerate the device and return LIBUSB_ERROR_NOT_FOUND
    or LIBUSB_SUCCESS accordingly.
    
    Fixes #169

    Add hotplug support to the Linux backend.
    
    There are two ways to configure hotplug support for Linux: udev, and netlink. It
    is strongly recommened that udev support is used on systems that utilize udev.
    We reenforce this recommendation by defaulting to --with-udev=yes at configure
    time. To enable netlink support run configure with --with-udev=no. If udev
    support is enabled all device enumeration is done with udev.

    Add hotplug support to the Darwin backend.
    
    Hotplug events are handled by the async event thread. This thread listens for
    two events: kIOTerminatedNotification, and kIOFirstMatchNotification. If
    either of these events fires the thread will iterate through the appropriate
    iterator and will either enumerate or call usbi_disconnect_device depending
    on the event.
    
    While adding hotplug support it was discovered that when reading from the IO
    registry we need to use kCFNumberSInt32Type for the device location. Using
    kCFNumberLongType would cause locations to be sign-extended and not match
    what is stored for the session id. This is now fixed.

    Add hotplug support. Bump the version to 1.0.15 and change the so version to
    reflect external API changes.
    
    The internal API is changing as follows:
     - Adding two new functions. usbi_connect_device, and usbi_disconnect_device.
       Backends must call these functions to add them to the context's device list
       at one of two places: initial enumeration (done at init), and on device
       attach and removal. These functions need to be called once per context.
     - Backends that support hotplug should not provide a get_device_list funtion.
       This function is now deprecated and will likely be removed once all backends
       support hotplug.
    
    The external API is changing as follows:
     - Two new functions have been added to register and deregister callbacks for
       hotplug notification: libusb_hotplug_register_callback(),
       libusb_hotplug_deregister_callback(). Hotplug callbacks are called by
       libusb_handle_events(). Details of the new API can be found in libusb.h.
     - A new capability check has been added to check for hotplug support. See
       LIBUSB_CAP_HAS_HOTPLUG.
    
    Aa suggested by Xiaofan add new example has been added to show how to use
    the new external hotplug API. See examples/hotplugtest.c.

    core: cache device descriptors in the core
    
    Discussion: It is necessary to cache the device descriptor in the core to
    support reading the descriptors after a device is disconnected. We could
    either 1) allow each backend to handle this caching (which would most
    certainly duplicate code), or 2) cache the descritors when a device
    is added. This patch does the later.
    
    Further discussion: It might be beneficial to cache more than just the
    device descriptors in the core. It might also be worthwhile caching the
    configuration and BOS descriptors as well.

    core: Keep a list of contexts (active_contexts_list) created by libusb_init. The list can be used by backends to determine which contexts need notification of device removal (and in the future device arrival). The active_contexts_list is protected from multiple access by the active_contexts_lock.

    Windows: Remove msvc/inttypes.h
    
    This file might have been needed for platform abstraction, except that
    all code shared among platforms doesn't need the file. Windows code in
    particular does not need to use the file.
    
    The file was used in one single place, where the PRIu64 define has now
    been replaced with it's value "I64u".

    io.c: Avoid timerfd race condition between completion and new submit
    
    An event handler thread working on transfer completion for the last
    flying transfer with a timeout can end up racing with a call to
    libusb_submit_transfer() from a second thread, so that the timerfd
    gets disarmed even though libusb actually again has a transfer with
    a timeout.
    
    By arming or disarming the timerfd during completion strictly
    according to remaining flying transfers while also holding the
    flying_transfers_lock this change ensures that a new transfer can
    not be added to the flying list until the completion code path has
    armed/disarmed the timerfd according to the current flying list.
    
    Hans de Goede describes the race condition situation in
    http://sourceforge.net/mailarchive/message.php?msg_id=29520709

    io.c: Only disarm timerfd when no flying transfer has a timeout
    
    Commit 4630fc22cff8ad3e1afa9b223378c0aabe282b5c made libusb work
    correctly when built to use timerfd but run on a kernel without
    timerfd support. The commit unfortunately also broke the logic
    during transfer completion which decides if the timerfd will be
    disarmed or not, and disarm_timerfd() was called even if the
    timerfd had already been armed with the next flying transfer
    timeout.
    
    Before the offending commit the timerfd would be disarmed only
    when arm_timerfd_for_next_timeout() reported that there was no
    flying transfer with a timeout. Let's restore that behavior.
    
    The bug was spotted through code review both by the author and
    by Hans de Goede, but was not squashed until Vincent Pellier
    experienced transfers never timing out, and helped confirm
    the source of the problem. Many thanks!

    Windows: Fix deadlock when submitting transfers
    
    The Windows backend needed to call usbi_fd_notification() from
    submit_transfer() because a new event source is added for every WinUSB
    transfer. This could cause a deadlock when attempting to lock the event
    lock if another thread was processing events on the just-submitted
    transfer.
    
    The deadlock comes about as the thread calling libusb_submit_transfer()
    acquires the transfer mutex before trying to acquire the event lock; this
    is the other order of lock acquisition from an event thread handling
    activity on the just submitted transfer. This could lead to one of two
    deadlocks:
    
    1) If the transfer completes while usbi_fd_notification() is waiting for
    the event lock and the callback attempts to resubmit the transfer.
    
    2) If the transfer timeout is hit while usbi_fd_notification() is waiting
    for the event lock then the attempt to cancel the transfer will deadlock.
    
    This patch fixes both of these deadlocks by having libusb_submit_transfer()
    only call usbi_fd_notification() after having released the transfer mutex.
    
    This deadlock was always present in the Windows code, but temporarily
    deleted by mistake in commit 6506013c6d4face34cfec79dd0584e9f528cbc6a
    and later restored in commit 325a8416697cf69b9b926ed68720f12b1aedf940.

    Linux: Search for /dev/usbdev<bus>.<device> USB device special files
    
    If neither the (now deprecated) usbfs filesystem nor udev is available
    then libusb searches for device nodes also in /dev where they may be
    created if the kernel was built with the option CONFIG_USB_DEVICE_CLASS.
    This helps on embedded systems such as Android, and all mdev users.

    Linux: Translate isoc packet status codes to LIBUSB_TRANSFER_ codes
    
    During testing of my usbredir code I hit a scenario where my libusb
    app was seeing EXDEV as status in the transfer's iso_packet_desc.
    
    This happened because we didn't translate linux negative errno errors
    in each isoc packet's status to LIBUSB_TRANSFER_ status codes! This
    patch adds these translations.

    Linux: Fix URB return code handling
    
    During testing of my usbredir code I hit a case where EOVERFLOW was not
    handled in handle_control_completion(). Instead of just fixing this one
    case I've audited (and fixed where necessary) all handle_foo_completion()
    functions to know about all errors documented in
    linux/Documentation/usb/error-codes.txt.
    
    Note that for handle_iso_completion() this patch actually removes the
    handling of some codes, since these can never occur on an iso urb (they
    can only occur on the iso packets included in the urb, see the next patch
    in this series). Also, in case an unknown status is encountered on an iso
    urb this patch sets the urb's status to ERROR rather then leaving it at
    completed.

    Don't print an error when libusb_cancel_transfer() fails with NOT_FOUND
    
    As stated in the documentation for libusb_cancel_transfer(),
    LIBUSB_ERROR_NOT_FOUND is an expected return value for
    libusb_cancel_transfer() under certain circumstances, so
    printing an error every time this happens is undesirable.
    
    Even more so because under Linux IOCTL_USBFS_DISCARDURB sets errno
    to EINVAL when the kernel can't not find the urb in the kernel's
    urbs-in-flight list, which means that the urb has already completed
    at the host controller level but it has not necessarily been reaped
    yet. IOW under Linux libusb_cancel_transfer() may yield a result of
    LIBUSB_ERROR_NOT_FOUND *before* the transfer's callback has been
    called! In conclusion there is no way for applications to avoid
    calling libusb_cancel_transfer() on already completed transfers,
    and these errors can and do happen frequently for some USB traffic.

    Linux: Fix cancel_transfer return value when cancelling a multi-urb transfer
    
    If we fail to cancel the last urb of a multi-urb transfer because it
    has already completed (errno == EINVAL on DISCARD_URB), then the entire
    transfer has already completed, so returning NOT_FOUND is consistent
    with what the documentation for libusb_cancel_transfer() says.
    
    But if we've successfully cancelled the last urb, and then another urb
    fails with errno == EINVAL, this means that we've still cancelled the
    transfer, as it has only *partially* completed.

    Windows: Fix build on VC++2003 which doesn't support variadic macros
    
    Change _MSC_VER tests to check for >= 1400 instead of > 1200 because
    Visual C++ did not support variadic macros until VC++2005, as per
    http://msdn.microsoft.com/en-us/library/ms177415%28v=VS.80%29.aspx
    
    Since usbi_dbg() is a function and not a macro with the old MS C
    compilers the functions guid_to_string() and windows_error_str()
    need to be compiled unconditionally, and the compiler should remove
    the dead code when debug logging is disabled on newer compilers.

    Add LIBUSB_TRANSFER_ADD_ZERO_PACKET flag to indicate need for ZLP
    
    Some protocols which use USB require an extra zero length data packet
    to signal end-of-transfer on bulk endpoints, if the last data packet
    is exactly wMaxPacketSize bytes long.
    
    This flag allows applications to inform libusb about this requirement,
    so that libusb can handle the issue transparently.
    
    At the moment the new flag is only supported on Linux, and submitting
    a transfer with the flag set returns an error at submit time on other
    systems. Hopefully implementations will soon follow for other systems.
    
    References #6.

    Do not call timerfd functions when timerfd is not being used
    
    When libusb was built with timerfd support but used on a system
    without timerfd support the library would hang indefinitely on
    completion of the first transfer, since timerfd functions were
    being called unconditionally and the error returned when timerfd
    was not being used caused a confused internal state.
    
    Many thanks to Ivo Smits for looking into the issue, proposing
    an initial solution, and helping with testing! Fixes #73.

    configure.ac: Darwin: Move -lobjc from LIBS to PC_LIBS_PRIVATE
    
    Since commit 40327cd134718475f6cec8935b856d4fdff2099c it is neccessary
    to explicitly include -lobjc not only when linking libusb itself, but
    also for programs linking statically against libusb. References #63.

    examples: Link only with ../libusb/libusb-1.0.la and not with -lusb-1.0
    
    Previous _LDFLAGS included both the freshly built libusb in ../libusb
    and -lusb-1.0, where libtool would usually resolve the latter to an
    already-installed libusb library in the system. The extra reference
    to a second libusb library resulted in failure to build examples on
    Mac OS X in some cases, and is plain wrong.

    libusb/Makefile.am: Avoid recursive variables in .rc silent-rule
    
    Not every make supports recursive variable expansion so some automake
    versions complain about non-POSIX variable names ever since commit
    70bec4a9f8ec28d36c731011fa24d37c74ad3523 which added support for
    silent-rules in our rule to compile the Windows .rc file.
    
    This commit removes the recursive variables and instead uses the
    simple and generic GEN message and associated variable.

    The example code and API doc for libusb_handle_events_timeout() could be
    interpreted as it being OK to pass a NULL pointer for the tv argument (I
    interpreted it like that when I first started coding for libusb).
    
    This patch changes the docs to make it clear that one must always supply
    a tv struct to libusb_handle_events_timeout.

    Linux: Fix #81 URB double free race condition on device disconnect
    
    A submitted transfer that has just been failed by the kernel could be
    picked up by an event handler to be cleaned up, where freeing of URB
    memory would race with the submit function doing it's own cleanup and
    freeing as a result of the submit failing.
    
    libusb_submit_transfer() always holds itransfer->lock, so the race can
    be avoided by taking that lock also in the cleanup path and checking
    that the URB memory has not already been freed before freeing it there.
    
    As http://libusb.org/ticket/81#comment:14 notes there is still another
    possible, but unlikely, race condition between libusb_submit_transfer()
    and an event handling thread. That will require more work to solve.

    Fix #56 race condition causing delayed completion of sync transfers
    
    The sync API had a race where it would check a condition to know if it
    needed to call a libusb_handle_events() function. However, the check
    was done outside of the lock that is held while the condition is set,
    so another thread could completely serve whatever was needed to make
    the condition true between it being checked and the event handler being
    called. This situation would be detected after a libusb-internal timeout
    of 60 seconds, after which the transfer would be completed without
    error, but with significant delay.
    
    Original patch at http://marc.info/?l=libusb-devel&m=127252114815709
    
    Changes by Hans de Goede:
    - Renamed the "race-proof" functions from libusb_handle_events*_check()

    Linux: Add __read_sysfs_attr() helper function
    
    On Linux we often need to read (postive) integers from sysfs. This patch
    adds a helper function for this. This is a preparation patch for adding
    a libusb_get_device_speed() function to libusb.

    Linux: Stop kernel from re-attaching in-kernel driver after reset
    
    When an interface is bound to the usbfs driver (iow claimed), the
    kernel will unbind it, and then after the reset do a device_attach
    on the interface, which will bind the default in kernel driver to
    the interface.
    
    So if an app has detached the in kernel driver, and claimed the
    interface and then does a libusb_reset_device. Things end up with
    the interface no longer being bound to the usbfs driver (so no longer
    claimed) and instead it is bound to the in kernel driver (iow the in
    kernel driver is re-attached).
    
    We can stop this from happening by releasing all claimed interfaces
    before the reset, as the kernel will not do the device attach after
    reset, if no driver was bound to the interface before the reset.

    Core: Use USB_MAXINTERFACES rather then sizeof(claimed_interfaces)
    
    claimed_interfaces is a long and thus its size differs on 32
    versus 64 bits, this patch uses USB_MAXINTERFACES instead of
    sizeof(claimed_interfaces) on interface number range checks
    for consistent behavior independent of the arch.

    In parse_interface() an unexpected descriptor would be parsed without
    validating the descriptor's length.  It is possible for size to be 0 at
    this point, which means that the parsing would read past the end of the
    source buffer.  Fix #83 by checking the length of the remaining buffer
    before parsing.

    Clean up in-flight transfers and device handle when closing a device
    
    Any in-flight transfers should properly invalidate their references
    to device handles that are being closed.  Additionally, they should be
    removed from the transfer-in-flight list.  This is done with the events
    lock held to protect against another thread processing the same transfer.
    The events lock is initialized as a recursive mutex, because the device
    close code might itself be called while an event is being handled.
    Fixes #82.

    Linux: Fix #70 race condition in sysfs_get_device_list()
    
    Change the way libusb chooses between using sysfs and usbfs for information
    about the attached devies.  Using the old method, a race condition could
    occur if a device was unplugged just before (or during) the call to
    libusb_get_device_list(), corrupting the internal sysfs_can_relate_devices
    and sysfs_has_descriptors variables and preventing libusb_get_device_list()
    from working in future calls.
    
    The old method was based on the assumption that if certain sysfs files
    (eg: busnum) could not be opened, that indicated an inadequacy of sysfs
    (ie: the running kernel's sysfs version did not contain those files),
    when in reality those files couldn't be opened because the device had
    been unplugged.
    
    The new method checks the adequacy of sysfs during libusb_init()
    (op_init()) and if a sysfs file cannot be opened, it is now assumed that
    it is because the device has been unplugged, not because sysfs is
    inadequate.

    Move library version number from configure.ac to libusb/version.h
    
    This is neccessary to support native MS builds. The Windows resource
    file libusb/libusb-1.0.rc must include the release version, which was
    previously only available after configure had run and had substituted
    the numbers into a generated libusb/libusb-1.0.rc file.
    
    The version atoms are now stored as CPP style #defines in libusb/version.h
    so that the .rc no longer needs to be generated but can simply include the
    header file and access the version information directly.
    
    The m4 macro LU_DEFINE_VERSION_ATOM() was added to configure.ac to get
    version atoms from libusb/version.h for use in AC_INIT(). The macro
    handles C and C++ style comments in version.h, but can easily be made
    to fail by obscuring the file. Please don't do that.
    
    Tested with MinGW using autoconf, and manual compile of libusb-1.0.rc
    using RC.EXE Version 5.2.3690.0 from Visual C++ 2005 Express Edition.

    Windows: Allow claiming any interface in composite device using WinUSB
    
    Issue reported by Benjamin Dobell, see #48. The call to
    WinUsb_QueryInterfaceSettings() is removed since it doesn't work
    on any other interface but the first (a WinUSB limitation).
    
    This allows the use of WinUSB.sys in lieu of the usbccgp.sys
    "USB Generic Parent" default driver for composite devices.

    Unlike bInterfaceNumber, bConfigurationValue does not have to be
    either sequential or contiguous. The bConfigurationValue is now
    included in debug output. Fixes #48 reported by Benjamin Dobell.

    The new variable name tries to clarify that libtool is being used.
    Linker flags must thus always be specified with -Wl.
    
    Factor out the libtool flag -no-undefined from host specific cases.
    The flag is required to build a Windows DLL, but is correct also for
    the other supported systems.
    
    Also, start actually using LTLDFLAGS in libusb/Makefile.am, so that
    libtool will see the options set by configure.

    Core: libusb_get_next_timeout() must consider all flying transfers
    
    If transfer->flags indicated that a transfer had a timeout, but no
    timeout was actually set, then libusb_get_next_timeout() would look
    no further for a timeout, ignoring any transfers later in the list
    which had a timeout set.
    
    Since libusb has an internal 60 second timeout this bug could not
    cause complete lockup, but it could cause a 60 second timeout even
    when a transfer was submitted with a shorter timeout.

    Linux: cancel URBs in reverse order
    
    In a multi-URB transfer, URBs should be cancelled in reverse order of

    is cancelled, data may be transferred for URB N+1 before it too can be
    cancelled). Fixes #8.

    Introduced calling convention (for Windows)
    
    Under Windows, a variety of compilers and configurations are available,
    meaning that the manner of parameter passing (e.g. registers vs stack)
    can vary.
    
    Match the Windows API calling convention and document this appropriately.
    This calling convention will be used regardless of the configuration of
    the user's development platform.
    
    The only user-level complication is that all functions used as libusb
    callbacks must use the same calling convention as libusb. The
    LIBUSB_CALL macro is provided to make this easy.

    Darwin: Cache device configuration value
    
    Cache device configuration value to bring the Darwin backend more in
    line with the libusb spec. To handle buggy devices GetConfiguration is
    not called unless the device has more than one configuration.

    Linux: fix log message that was being unconditionally sent to stderr (#44)
    
    This message was put in place to aid libusb-compat-0.1 users, who
    may run into the change that libusb-0.1 allowed you to usb_open() a
    device that you don't have write access to, but libusb-1.0 does not.
    
    As explained on the ticket this change is dangerous so it should go through
    the usual logging mechanism. I also added a similar regular log message
    to libusb-compat-0.1.

    'interface' is a preprocessor #define already associated with COM on Windows,
    that can cause a conflict as soon as windows.h is included.
    
    There are a few more places where interface is still used, which should
    be changed for libusb-2.0

    libusb_cpu_to_le16: macro->static inline function
    
    The libusb_cpu_to_le16 macro was a ({ ... }) expression, which
    generates the following compiler warning every time it is used,
    (and that is several times for every #include <libusb.h>):
    
    libusb.h:880: warning: ISO C forbids braced-groups within expressions
    
    With this patch, #include <libusb.h> stops generating compiler
    warnings on gcc 4.4.
    
    As libusb.h heavily relies on the use of static inline functions
    those can be relied on to work properly, and there should not be
    any significant difference in the code the compiler generates.

    Add internal abstraction for POSIX Threads
    
    This prepares for a Windows backend without dependency on pthreads-w32.
    
    pthread_* is renamed to usbi_* and PTHREAD_* to USBI_*.
    
    A usbi_mutex_static_t and usbi_mutex_static_lock() and _unlock() are
    introduced for statically initialized mutexes, since they may be
    implemented using other types when pthreads mutexes aren't used.
    
    Move -pthread from libusb/Makefile.am to host-specific THREAD_CFLAGS in
    configure.ac. This will enable optional use of -lpthread for cygwin.

    Linux: Fix endianness handling of usbfs config descriptors (#27)
    
    driver/usb/core/devio.c function usbdev_read translate the follwing files
    to CPU endianess:
    
    le16_to_cpus(&temp_desc.bcdUSB);
    le16_to_cpus(&temp_desc.idVendor);
    le16_to_cpus(&temp_desc.idProduct);
    le16_to_cpus(&temp_desc.bcdDevice);
    
    All other data is passed without any change.
    
    libusb/os/linux_usbfs.c calls usbi_parse_descriptor with host_endian=1
    for config descriptors. According to the kernel code, they must be
    processed with host_endian=0, as they are not translated by the kernel.

    Use timerfd for timeout handling
    
    Use a new file descriptor from the timerfd system calls to handle
    timeouts. On supported systems, this means that there is less hassle
    figuring out when the poll() timeout should be, since
    libusb_get_next_timeout() will always return 0 and the timeout events will
    be triggered as regular activity on the file descriptor set.
    
    Add API function libusb_pollfds_handle_timeouts() to detect whether
    you're on a platform with the timing headache, and flesh out the
    surrounding documentation.

    Linux: Add support for the new URB_BULK_CONTINUATION flag
    
    Add support for the new USBDEVFS_URB_BULK_CONTINUATION flag to libusb.
    
    This flag, which is expected to be available in usbfs starting with
    kernel 2.6.32, allows the kernel to cancel multiple URBs upon receipt
    of a short packet.  This capability allows libusb to preserve data
    integrity of large bulk transfers that are split into multiple URBs.
    Without this support, these URBs must be canceled in userspace upon
    receipt of a short packet, a race condition against future transfers
    which might partially fill these canceled URBs.
    
    This patch automatically detects whether a supported kernel is present
    and enables the use of the flag when possible.
    
    [dsd: tweaks to supported kernel detection, and some inline
     documentation of this mechanism]

    Transfer locking
    
    At least on Linux, there were some possible races that could occur if
    a transfer is cancelled from one thread while another thread is handling
    an event for that transfer, or for if a transfer completes while it is
    still being submitted from another thread, etc.
    
    On the global level, transfers could be submitted and cancelled at the
    same time.
    
    Fix those issues with transfer-level locks.

    Linux: more flexibility with monotonic clock
    
    Some users have reported that CLOCK_MONOTONIC does not work on their
    systems - I suspect it is available on x86 but perhaps not some
    of the more uncommon architectures. We should fall back on
    CLOCK_REALTIME in these cases.
    
    Also, CLOCK_MONOTONIC_RAW seems even more monotonic, so we should use
    that if it is available.
    
    We now test different clock IDs during initialization to find the
    best one that works.

    Make synchronous transfer APIs robust against signal interruption
    
    libusb_control_transfer and libusb_bulk_transfer are designed to be
    synchronous such that control is not returned until the transfer
    definitively succeeds or fails.  That assumption is violated if a signal
    interrupts these functions because there is no way for the application
    to continue waiting for the transfer without resubmitting it.  This
    patch changes these synchronous APIs so they do not abort in the case of
    a signal interruption.

    Prevent transfer from being submitted twice or improperly canceled
    
    This ensures that tpriv->urbs and tpriv->iso_urbs are always set to NULL
    whenever a transfer is not submitted.  In this way, submit_*_transfer()
    and cancel_*_transfer() can error check to ensure that the transfer is
    in the correct state to be either submitted or canceled, preventing
    potential memory leaks or double frees.

    Linux: Fix race condition in cancel_bulk_transfer()
    
    This fixes a race condition in cancel_bulk_transfer().  In the old
    version, awaiting_reap and awaiting_discard are incremented in
    cancel_bulk_transfer() and decremented in handle_bulk_completion().
    However, since these events may take place in two different threads,
    these variables may reach zero before all URBs have been canceled,
    triggered spurious callbacks and duplicate frees.
    
    This changes the logic to use a single variable "num_retired" to replace
    both awaiting_reap and awaiting_discard.  num_retired is incremented
    only in handle_bulk_completion() and thus there is no race.  The handler
    will know that all URBs have been canceled when num_retired becomes
    equal to num_urbs.
    
    This change also simplifies a great deal of the logic in both functions
    and is a net reduction in the amount of code.
    
    Note that some variables such as "reap_action" probably need to still be
    protected by a mutex, and this patch does not address that issue.

    Pause event handling while opening and closing devices
    
    Ludovic Rousseau found that crashes often occur if you close a device
    while another thread is doing event handling.
    
    Fix this by adding an internal control pipe, which the close routines
    use to interrupt the event handler and obtain the event handling lock,
    ensuring that no other thread is handling events while the device is
    closed. After the close completes, it signals all the event handlers
    to start up again using the usual mechanism.
    
    Also modified libusb_open() to do a similar thing, so that event
    handlers are interrupted in order to realise that a new poll fd has
    appeared.

    Reset internal transfer flags on submit
    
    This fixes a problem pointed out by Lou, where resubmitting a transfer
    that previously timed out never timed out again, as if the timeout had
    been set to 0.

    without breaking things. Not sure that I want to support this properly,

    This reverts commit 2d3a1111caff40ebb87983c861ff548cdc9e5946.
    This was based on the assumption that dying threads would automatically
    release mutexes, which is not the case.

    a fix for SIGSEGV in handle_bulk_completion()
    
    We cannot dereference tpriv after calling

    the user-supplied callback which may free the transfer.

    Temporary workaround for event handling serialization issue
    
    Ludovic Rousseau pointed out that libusb_unlock_events() is not called
    when a thread gets terminated with a signal, meaning that event waiters
    will not be woken up in this case.
    
    Add a temporary hack to libusb_event_handler_active() so that at least
    the other threads will realise on the next iteration of their event
    handling loop.
    
    The real fix will likely involve reworking most of this.

Author: Daniel Drake <dsd@gentoo.org>
Date:   Thu May 29 12:35:01 2008 +0100

    Refine libusb_set_configuration() semantics
    
    Applications will generally want to set a configuration before claiming
    interfaces. The problem is that the interface may already be set, and
    someone else may have claimed an interface (meaning that all calls to
    set_configuration will fail, even if it's for the same configuration).
    
    There are now 2 options:
    1. Use the new libusb_get_configuration() to determine active
       configuration before calling libusb_set_configuration()
    2. Or just call libusb_set_configuration() as usual, which will do
       nothing if that configuration is already active.

    doing the event handling. Complicates things for MT async apps, but
    then again it's a bit of a tricky combination to start with.

    Linux: fire multiple URBs at once for split transfers
    
    This results in a significant performance increase for bulk transfers
    larger than 16kb, and fixes a bug where data would be spliced and mixed
    between two simultaneously submitted transfers to the same endpoint.
    
    It also allows isochronous transfers larger than 16kb to be submitted.
    
    This commit also improves cancellation - the library now understands
    what is going on.

    Isochronous endpoint I/O
    
    Due to variable-sized structures, this involved changing allocation

    libusb.
    
    A synchronous function is missing, and I could do with writing a few
    more helper functions to simplify things.

    Separate transfer allocation and submission
    
    Leads to some hefty API changes. Now we're much more similar to the
    Linux kernel model.
    
    Problems with dealing with asynchronous control transfers are passed
    on to the user, basically you must allocate a buffer, start with the
    setup, and put the data after. This won't make much sense until
    documented (soon...)

    libusb_transfer is now a kind of transfer handle. To reduce confusion

    renamed to libusb_{control,bulk}_transfer_request.

    Persistent libusb_device storage
    
    Devices are now assigned a session ID (currently busnum:devaddr) which

    libusb_device structure instances.

    Add convenience function to find and open a device by USB VID+PID
    
    Lots of libusb apps I write are simple test apps not intended to be real
    apps. Having a function available to quickly locate my device will be
    handy in such situations.

    Rework device discovery API
    
    libusb_find_devices and libusb_get_devices are no more
    
    libusb_get_device_list obtains a list of libusb_device structures for all
    known devices in the system.
    
    Each libusb_device now has a reference count, defaulting to 1 on
    instantiation. The reference count of 1 refers to the fact that it is
    present in the list in this scenario.
    
    Opening a device adds a pointer to the libusb_device structure in the
    handle, so that also adds a reference. Closing the device removes that
    reference.
    
    The function to free the device list can optionally unref all the devices
    inside.
    
    In future we will make the libusb_device instances all "global" so that if
    the app calls get_device_list twice it actually gets the same libusb_device
    structure references back. This way we can start to track disconnects, and
    we can investigate adding a unique "session ID" to each libusb_device, an
    identifier guaranteed to be unique to that device until reboot.

    Don't pass ctrl_msg/bulk_msg structures through async paths
