There's more to it. We need to move the 
add(MediaStreamTrack)/remove(...) functions and the event handler 
attributes as well.

I think the track lists should be attributes on MediaStream similar to 
the track lists on the media elements; it's not possible with sequences. 
A sequence is also about order which is the thing we want to move away from.
