src/llist.c: Add llist_next_filter()
This convenience function can be used to return the successor of a list
item if it is matched by a filter callback and return NULL otherwise.
We will use this for an improved version of the LLIST_FIND_FOREACH macro
that can be used whenever results are known to be continuous.
