Suggestion: this method should be renamed to setNativeTrack. Probably worth
doing as a cleanup.

Well - setExtraData is a blink method. And the base class is a
blink::WebMediaStreamTrack::ExtraData. 
In blink we also have blink::WebMediaStreamSource::ExtraData and
blink::WebMediaStream::ExtraData that all work the same way. 

All in all, I can't change it and I don't think its worth getting help to rename
them and all locations in Chrome that call them.

Okay. What I mean is a cleanup for future. :)
