/**
 * list - double linked list routines
 *
 * The list header contains routines for manipulating double linked lists.
 * It defines two types: struct list_head used for anchoring lists, and
 * struct list_node which is usually embedded in the structure which is placed
 * in the list.
 *
 * Example:
 *	#include <err.h>
 *	#include "list/list.h"
 *
 *	struct parent {
 *		const char *name;
 *		struct list_head 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];
 *		for (i = 2; i < argc, i++) {
 *			c = malloc(sizeof(*c));
 *			c->name = argv[i];
 *			list_add(&p.children, &c->list);
 *			p.num_children++;
 *		}
 *
 *		printf("%s has %u children:", p.name, p.num_children);
 *		list_for_each(&p.children, c, list)
 *			printf("%s ", c->name);
 *		printf("\n");
 *		return 0;
 *	}
