Convert convert.c to struct object_id. Add a use of the_hash_algo to replace hard-coded constants and change a strbuf_add to a strbuf_addstr to avoid another hard-coded constant. Note that a strict conversion using the hexsz constant would cause problems in the future if the internal and user-visible hash algorithms differed, as anticipated by the hash function transition plan.
