/**
 * tlist - typesafe double linked list routines
 *
 * The list header contains routines for manipulating double linked lists;
 * this extends it so you can create list head types which only accomodate
 * a specific entry type.
 *
 * Example:
 *	#include <err.h>
 *	#include <stdio.h>
 *	#include <stdlib.h>
 *	#include <ccan/tlist/tlist.h>
 *
 *	// We could use TLIST_TYPE(children, struct child) to define this.
 *	struct tlist_children {
 *		struct list_head raw;
 *		TCON(struct child *canary);
 *	};
 *	struct parent {
 *		const char *name;
 *		struct tlist_children children;
 *		unsigned int num_children;
 *	};
 *
 *	struct child {
 *		const char *name;
 *		struct list_node list;
 *	};
 *
 *	int main(int argc, char *argv[])
 *	{
 *		struct parent p;
 *		struct child *c;
 *		unsigned int i;
 *
 *		if (argc < 2)
 *			errx(1, "Usage: %s parent children...", argv[0]);
 *
 *		p.name = argv[1];
 *		tlist_init(&p.children);
 *		for (i = 2; i < argc; i++) {
 *			c = malloc(sizeof(*c));
 *			c->name = argv[i];
 *			tlist_add(&p.children, c, list);
 *			p.num_children++;
 *		}
 *
 *		printf("%s has %u children:", p.name, p.num_children);
 *		tlist_for_each(&p.children, c, list)
 *			printf("%s ", c->name);
 *		printf("\n");
 *		return 0;
 *	}
