[webrtc-pc] Pull Request: Update a receiver's set of remote streams when "a=msid" lines change.

taylor-b has just submitted a new pull request for https://github.com/w3c/webrtc-pc:

== Update a receiver's set of remote streams when "a=msid" lines change. ==
Fixes #1609.

This PR updates the `[[AssociatedRemoteMediaStreams]]` slot in every
`setRemoteDescription` call, even if the direction isn't changing, and
also adds:

- A `getStreams()` method to `RTCRtpReceiver`, just returning the value
  of the internal slot.
- A `streamsupdated` event, to tell when the set of stremas changes.
  Fired at the end of `setRemoteDescription` like everything else.
