refs: convert read_ref and read_ref_full to object_id
All but two of the call sites already have parameters using the hash parameter of struct object_id, so convert them to take a pointer to the struct directly. Also convert refs_read_refs_full, the underlying implementation. Signed-off-by: brian m. carlson <sandals@crustytoothpaste.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
