Re: [webrtc-pc] [[ReceiveCodecs]] is only set on answer. How to achieve early media? (#2369)

My first inclination is to say that [[ReceiveCodecs]] should contain all codecs that have been assigned a definition, which means all PTs from all offers and answers processed for that media section.
That means updating whenever we send *or* receive *either* an offer *or* an answer.
It's possible to negotiate changes to the codec parameters, but not the basic existence of the codec for the PT (I don't think the a=rtpmap line can change, ever, but at least for H.264, the a=fmtp line can) - but I *think* (offhand) that negotation only affects [[SendCodecs]] - what we can receive is unaffected; it's only determined by our reception capabilities.
