Subject: [PATCH 15/36] security: detect object containment violations at the
 IR level

It is more efficient to check for object containment violations at the IR
level instead of in the protocol handlers.  OStatus containment is especially
a tricky situation, as the containment rules don't match those of IR and
ActivityPub.

Accordingly, we just always do a final containment check at the IR level
before the object is added to the IR object graph.

 transmogrifier tests

Some objects were not completely rewritten in the tests, which caused object
containment violations.  Fix them by rewriting the object IDs to be in an
appropriate namespace.
