Once the call is established between browsers, video deteriorates

responds with 'ccm fir' and video keeps good quality throughout.
We did a major rewrite of the negotiation code in 37, and in 38 added
multistream and bundle (and a lot of fixes for things); so it's
certainly possible there was a regression in 38. Did 37 (or 36)
answer in the same way to a "ccm fir"-only offer?
I'm pretty sure this was the behavior all along;
signaling_unittests has several test-cases that require the answerer to
add rtcp-fbs that weren't in the offer.
