Having read the discussion about uncertainty on DOMError etc. I think we should have something that is not unstable and that we can write applications that use. 

I propose we move that back to an RTCError object that includes a message field.

In particular, I'm more than a little agitated that we've thrown away our "message" field that we were using before. This provided invaluable diagnostic information for developers. Is there some reason *why* we can't derive RTCError from DOMError in the same way as we're apparently doing for RTCSdpError? (While we're at it, I'll point out that simply saying "something is wrong on line x, you go figure it out" is a bit unsatisfying as well -- we should have a "message" field here as well.)
