Browse Source 
- 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.
