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. Intent to prototype: https://groups.google.com/a/chromium.org/g/blink-dev/c/65YdUi02yZk Bug: chromium:1051821 Change-Id: If963beed37e96eed2dff3a2822db4e30caaea4a0 Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/198126 Reviewed-by: Harald Alvestrand <hta@webrtc.org> Commit-Queue: Markus Handell <handellm@webrtc.org> Cr-Commit-Position: refs/heads/master@{#32860}
