Here's the cold-turkey webidl akin to what Giri had (I don't think we 
need to spec the transition API):

interface MediaDevices : EventTarget {
     attribute EventHandler ondevicechange;
     Promise<sequence<MediaDeviceInfo>> enumerateDevices (); // can fail 
yay!
};

partial interface NavigatorUserMedia {
     Promise<MediaStream> getUserMedia (MediaStreamConstraints constraints);
};

partial interface MediaDevices {
     static MediaStreamConstraintSet getSupportedConstraints (DOMString 
kind);
     Promise<MediaStream> getUserMedia (MediaStreamConstraints constraints);
};

[NoInterfaceObject]
interface ConstrainablePattern {
MediaStreamConstraintSet  getCapabilities ();
MediaStreamConstraints    getConstraints ();
MediaStreamConstraintSet  getSettings ();
     Promise<void> applyConstraints (MediaStreamConstraints constraints);
     attribute EventHandler onoverconstrained;
};

I'll work on a pull request.
