This change adds a parser for the x-mt line to the WebRTC SDP, and adds a collection in the SessionDescription for media transport.
x-mt line contains information about media transport settings.
This is an experimental line.
This change will be followed up by two other changes:
* Setting the offer with x-mt
* Using the x-mt line to pass it to the media transport

In the January 22nd 2019 WebRTC meeting it was agreed that an offer
for sending (or receiving) simulcast should only contain the RIDs
of the layers that are sent by the client.
This change removes the complexity that was added to support sending
and receiving the single layer (and RID) that are sent from the server.
