Convert all the uses of unsigned char [20] to struct object_id. Also, convert some hard-coded integers into constants.
name_rev_line accepts a wide variety of free-form input and only interprets 40-character hex values, passing through everything else. Consequently, it is not a good candidate for parse_oid_hex, which is much stricter.
This change is a prerequisite for converting parse_object.
