object: convert internal hash_obj() to object_id

Now that lookup_object() has an object_id, we can consistently pass that around instead of a raw sha1. We still convert to a hash to pass to sha1hash(), but the goal is for that to go away shortly. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
