The ufrag is available in event.candidate.usernameFragment.  Unless I'm
mistaken, the pwd is not, it requires parsing the local description.

The m-line is available in event.candidate.sdpMid, so no objection to
making it compulsory, even though I don't see how it is useful since we
mandate bundling.
