This CL removes (almost) the last RTP references in VideoReceiveStream. There are still references to RTPFragmentationHeader and SSRCs, which will be dealt with later. There are also new GUARDED_BY and thred checker added to the synchronization class. When there are othre transports than RTP, there will instead be an interface + inheritance for RtpStreamReceiver and RtpStreamSynchronizattion in VideoReceiveStream. This work will be done when we actually know how we want to make thee transport interface.
