builtin/replace: convert to struct object_id
Convert various uses of unsigned char [20] to struct object_id. Rename replace_object_sha1 to replace_object_oid. Finally, specify a constant in terms of GIT_SHA1_HEXSZ. Signed-off-by: brian m. carlson <sandals@crustytoothpaste.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
