Moving usage of bitrate configuration related interface from Call interface to the corresponding methods in the RtpSendTransportController interface. SetBitrateConfig was replaced with SetSdpBitrateParameters SetBitrateConfigMask was replaced with SetClientBitratePreferences OnNetworkRouteChanged was replaced with OnNetworkRouteChanged This makes it more clear that RtpSendTransportController owns bitrate configuration and fits a longer term ambition to reduce the scope of the Call class.
