Add diff_gid_lists() with test

This patch adds a new call which compares a list of current GIDs with a
list of new GIDs and return a list of GIDs which are currently missing
and must be added and another list of GIDs which are not used anymore
and must be deleted. The method is the same as used by
diff_string_lists().
