Hi,

This patch includes the changes I previously sent in 
http://www.ethereal.com/lists/ethereal-dev/200605/msg00208.html (I 
assume it wasn't committed).  The combined patch:

- shows profile-specific extension data at the end of SR/RR reports (if 
packet length has not yet been reached after parsing normal data) and 
advances offset (further packets were not recognised+dissected as this 
data wasn't being skipped).
- checks that the length of the RTCP data in the whole frame matches the 
combined length from the length fields (the last check in RFC 3550, "A.2 
RTCP Header Validity Checks") with a generated field and expert info 
when wrong.
- reports the length field in all of the message types consistently (the 
length was confusingly shown multiplied by 4 only in APP packets...)

Best regards,
Martin
