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.
