WebRTC: Update the MediaStream API

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Adam Bergkvist]

Update the MediaStream API to match the latest Media Capture and Streams specification [1].

In WebKit, the MediaStream API is mainly implemented by MediaStream and MediaStreamTrack with their corresponding platform representations, and RealtimeMediaSource.

Nit: you could use copyValuesToVector here.

This should be "enum class".

Thanks Eric for reviewing. I'll let the EWS complete before setting cq+.
