refs/iterator: implement seeking for files iterators
Implement seeking for "files" iterators. As we simply use a ref-cache iterator under the hood the implementation is straight-forward. Note that we do not implement seeking on reflog iterators, same as with the "reftable" backend. Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>
