Here we see the same pattern again, but this time the @@ lines give better context: these are actually hash I/O. Maybe it's about time we add

int oidwrite(char *, size_t , const struct object_id *); // optionally, void strbuf_addoid(struct strbuf *, const struct object_id *); int oidread(struct object_id *, const char *, size_t);

for conversion from between an object_id in memory and on disk? It would probably be a straight memcpy for all hash algorithms so we don't really need new function pointers in git_hash_algo for this.
