None of the callbacks actually care about having a "struct object"; they're happy with just the oid and type information. So let's give ourselves more flexibility to avoid having a "struct object" by just passing the broken-down fields. Note that the callback already takes a "type" field for the fsck message type. We'll rename that to "msg_type" (and use "object_type" for the object type) to make the distinction explicit.
