[webrtc-extensions] RTP header extension control: Incompatible extensions (#239)

alvestrand has just created a new issue for https://github.com/w3c/webrtc-extensions:

== RTP header extension control: Incompatible extensions ==
In some cases, the set of extensions in an answer needs to be a subset of the offered extensions, and this needs to be reflected in [[NegotiatedExtensions]], even when the incoming answer is offering the extension.

(The current case is that the transport-sequence-number extension needs to be turned off when CCFB is in use)

To correct, add a step to section 5.2, when processing _negotiatedExtensions_, allow the UA to modify the set of accepted extensions to be consistent with the PeerConnection state.
