API change! rc_ls_dir, rc_get_config and rc_get_list no longer take
a starting list as a first argument. Instead, use rc_strlist_join
to append or prepend the new list to an existing list.
API change! rc_strlist_add and friends now take char *** instead of
char ** and return a pointer to the item added instead of the new
list head. This is so we can easily tell if the item was successfully
