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 have a fix for this in the pinefrog-1.4 branch. However, lmadsen did not
want to include that in the 1.4 release he's working with, so I'll put it
on hold until the management feels like fixing stuff.

Meanwhile, feel free to test pinefrog-1.4. I will upgrade those patches to
pinefrog-trunk after a while of testing and ask for permission to merge it
into trunk.
