sha1_file: introduce an nth_packed_object_oid function
There are places in the code where we would like to provide a struct object_id *, yet read the hash directly from the pack. Provide an nth_packed_object_oid function that is similar to the nth_packed_object_sha1 function. In order to avoid a potentially invalid cast, nth_packed_object_oid provides a variable into which to store the value, which it returns on success; on error, it returns NULL, as nth_packed_object_sha1 does.
