0000204: move llist_add_to_end() to libbb and add llist_free()

Notes
(0000200) bernhardf 05-02-05 10:02	I retract this patch (The snippet against xargs would have to be redone proper, awk, sed and possibly other should be converted too). xlist_t may better be dropped in favour of libbb.h's typedef struct llist_s { char data; #ifdef LLIST_LENGTH size_t length; #endif struct llist_s link; } llist_t; Also, these should be implemented and perused throughout list-using code, i guess: extern llist_t llist_add_to(llist_t old_head, char new_item); extern llist_t llist_add_to_end(llist_t list_head, char data); extern void llist_free_one(llist_t llist); extern void llist_free(llist_t llist);

(0000597) bernhardf 10-04-05 07:29	llist_add_to_end was moved from ifupdown.c to libbb/llist.c. Closing this bug now, although a couple of applets should peruse llist_t instead of reinventing the wheel over and over..
