Subject: [PATCH 06/11] From Peter Lemenkov via
https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=8326
Dissector for the Sippy RTPproxy controlling protocol. RTPproxy is a well-known
(among SIP-engineers) application and it operates using its own simple
text-based protocol. There are several competing products but all of them
implements it (sometimes slightly extending).

Add a cast to try and fix
packet-rtpproxy.c:226: warning: implicit conversion shortens 64-bit value into
a 32-bit value
I'm not quite sure what's going on here, all the values in use are either gint
or guint so they should all be the same size?
svn path=/trunk/; revision=51419
Take another stab at
packet-rtpproxy.c:226: warning: implicit conversion shortens 64-bit value into a
32-bit value
svn path=/trunk/; revision=51420
One more 64/32-conversion fix for rtpproxy
svn path=/trunk/; revision=51421
Fix Coverity CID 1063335: Unused pointer value.
svn path=/trunk/; revision=51430
