Summary:                    wrong parsing of received RTCP packets
Description: 
The code for parsing the RTCP packets is buggy. When an RTCP RR/SR frame is
handled, it expects some fields present although they are optional.

E.g. take a look at the RTCP packets in the attached pcap dump. The first
RTCP packet contains a RR without any RTP statistics data. Nevertheless
Asterisk sets the statistics, reading wrong data from the RTCP packet (the
following SDS).

---------------------------------------------------------------------- 
I just went through this code in 1.4 and it's very buggy. It just parses
the first report in a compound packet, ignoring the SDES and misbehaves in
many ways. I guess that the new code is not much better, even though there
has been some improvements in how we aggregate data.
