Firefox does not support "pranswer" and Chrome breaks ICE/DTLS things
if "pranswer" is used.

I still see the "pranswer" monster in the WebRTC 1.0 draft. We don't
need it. It can be perfectly emulated via JS by means of (assuming

1) pc.createOffer() => offer

2) pc.setLocalDescription(offer)

3) Send INVITE

4) Receive 183 with SDP

5) pc.setRemoteDescription(pranswer)

6) Receive 200 with SDP

7) pc.setLocalDescription(pc.localDescription)

8) pc.setRemoteDescription(answer)

"pranswer" is the ugliest and most useless stuff in WebRTC API and
nobody implements/uses it.

Can we get rid of it before 1.0.0 is out?
