This changes adds exposure of a new transceiver method for accessing header extensions that have been negotiated, following spec details in https://w3c.github.io/webrtc-extensions/#rtcrtptransceiver-interface. The change contains unit tests testing the functionality. Note: support for signalling directionality of header extensions in the SDP isn't implemented yet. https://chromestatus.com/feature/5680189201711104.
