index: future proof for "extended" index entries

We do not have any more bits in the on-disk index flags word, but we would need to have more in the future. Use the last remaining bits as a signal to tell us that the index entry we are looking at is an extended one. Since we do not understand the extended format yet, we will just error out when we see it. Signed-off-by: Junio C Hamano <gitster@pobox.com>
