+Initially provided a bfd containing an archive and NULL, opens a bfd
+on the first contained element and returns that. Subsequent calls to
+bfd_openr_next_archived_file should pass the archive and the previous
+return value to return a created bfd to the next contained element.
+NULL is returned when there are no more.
