The fallback behaviour is well defined by the rfc (ignore the other offers), so
we can implement the fallback behaviour for the undrafted Call spec without any
extra effort. I'm marking this as later.

To do full cap-neg support, the CM could add an optional interface for cap neg
which contains the other possible configurations as lists of
MediaDescriptionMaps (possibly with some compression with numbered descriptions
like how the RFC does it). If the client supports it, then everything is
peachy. Otherwise it gets ignored, and we're also good.

I'm assuming here that clients are allowed to ignore MD interfaces they don't
understand in MDOffers. We should probably specify that.
