Piotr (Peter) Slatala 13e570fcb0 Add a parser for the x-mt line.
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
