Intent to ship: Identity provider proxy for WebRTC

[Martin Thomson]

As of 2015-04-15 I intend to turn identity for WebRTC on by default.
It has been developed behind the media.peerconnection.identity.enabled
preference. Firefox will be the first to implement this; I have only
informal promises from Google to implement once we ship.

This feature is the mutual authentication mechanism for WebRTC [1].
It enables peer-to-peer media communications that are confidential,
even from the site that you are visiting. We don't currently have UX
[2] for this, so enabling the feature is largely intended to enable
experimentation. This is feature will be needed for Firefox Hello.

This feature was previously discussed in this "intent to implement"
thread: <https://groups.google.com/d/msg/mozilla.dev.platform/QiF18J4vccA/rDclGYmFPBEJ>.
