Subject: - add llist_free_one() and llist_free() to libbb; Add a bit of
 documentation. - change llist_add_to_end as proposed by vodz in
 http://busybox.net/lists/busybox/2005-September/016411.html - remove unneeded
 includes, add short boilerplate and copyright to llist.c - move COMM_LEN from
 find_pid_by_name to libbb.h and use it in procps_status_t - add
 reverse_pidlist() to find_pid_by_name. Will be needed for pidof.
