[Live-devel] Updated code to handle RTCP "RR" packets

[Ross Finlayson]

Thanks to code contributed by Clark Taylor, I have updated the "RTPSink" 
implementation so that it now processes incoming RTCP "Receiver Report" 
(RR) packets - analogous to the way that the "RTPSource" implementation 
already processes incoming RTCP SR packets.

(Clark, could you please check that the new version of the code works the 
way that you expect?)
