Adds generic management of RTCP functions to an RTP data queue.
Extends an RTP data i/o queue adding management of RTCP functions:
Provide feedback on the quality of the data distribution.
Convey the CNAME (persistent transport-level identifier) for every RTP source.
Control the sending rate of RTCP packets
Convey minimal control information about the participants
This class implements generic RTCP behaviour (as specified in RFC 1889/draft-ietf-avt-rtp-new) and may be specialized for specific profiles (see AVPQueue) or particular RTCP extensions.
