platform-external-webrtc/webrtc/modules/rtp_rtcp/source/rtcp_receiver_unittest.cc
Peter Boström fe7a80c38c Prevent sender RTCP signals for receive-only channels. 
Since RTCP packets are delivered to both senders and receivers that
correspond the receivers currently log that NACKed packets are missing,
since they have no direct connection to the sending side or the RTP
packet history. Also preventing triggering on SR requests and PLI/FIR.
