Replace several hard-coded full and partial object IDs with variables or computed values. Create junk data to stuff inside an invalid tree that can be either 20 or 32 bytes long. Compute a binary all-zeros object ID instead of hard-coding a 20-byte length.
Additionally, compute various object IDs by using test_oid and $EMPTY_BLOB so that this test works with multiple hash algorithms.
