Wireshark-bugs: [Wireshark-bugs] [Bug 10364] Warning for SIP 200 OK response with Contact header

Comment # 5 on bug 10364 from
The comment in the code is actually right - it goes against RFC 3261 to send a
Contact with expires=0 back in the response, since a response to a REGISTER is
only supposed to contain *current* bindings, not removed ones. Nor did RFC 5626
(which added the "reg-id" param) change that behavior.

But 3GPP has bent the rules before for their profile of SIP, so we might as
well ignore the Contact being there. (i.e., not issue an expert warning) Or
change it to PI_NOTE instead of PI_WARN.
