The channel classes have stored the negotiated headers but a more natural place to store them is in the RtpTransceiver class where RtpHeaderExtension state is managed as well as the implementation of the only method that depends on the stored state, HeaderExtensionsNegotiated(). Also adding a TODO for further improvements where we're unnecessarily storing state in the channel classes for the purposes of the transports.
