Although async transfers are meant to use heap memory, we never return before the transfer function has completed so stack memory will suffice for control transfers, fixing a memory leak in the process.

Do not attempt to clear a usb halt before sending the cancel message since all transfers should normally be cancelled before attempting to clear a halt condition, and only change the return message to a timeout if it's consistent with a cancellation.

We are always dependent on libusb handling events so use the blocking libusb_handle_events in the polling thread and use a bool to know if we should continue polling.
