Where "TRANSPORT attributes" refers to: https://tools.ietf.org/html/draft-ietf-mmusic-sdp-mux-attributes-16 The BUNDLE draft now says that these attributes can (in fact, MUST) be omitted when m= sections are bundled (they only need to go in one of the bundled m= sections), so we should start accepting that SDP. This CL doesn't fix "a=rtcp-mux", unfortunately. That will be easier to fix once we've split apart an "RtpTransport" object from BaseChannel.
