Plugged a possible race condition in completing fax transmission, not actually seen, but noticed when looking for something else.
Added first try at functions to get presentation token in conference, only H.239 version so far.
Change OpalMediaSession to be a PSafeObject, avoids some nasty race conditions.
Fix for assert in jitter buffer "on time" delay reduction when getting quite close to one packet time.
Fixed issue with waiting until end of releasing first connection, before releasing second connection in call. The second connection can get confused when the first connection starts doing things like shutting down media streams, thinking this is "in call" actions. Now when one is released the other is released immediately. To avoid problems with transfer mechanisms, it only does this if precisely two connections in call.
Fixed uninitialised member variable, thanks Bob Reif
Fix for media session race condition (change to PSafeObject) can cause deadlocks now. Fix for that added.
Removed domain test of TLS certificate CN if calling by IP address.
Fixed TLS incoming connection getting correct local interface address.
Added indication on OpenPhone status that media is secured (SRTP)
Fixed build without SRTP
More presentation role token work, including adding test menu to OpenPhone.
Be more forgiving of incorrect SAVP indication in SDP. If have "crypto" attribute, then must be SAVP even if it says AVP.

Fixed default FMTP parameter, when missing, for telephone-event in SDP.
Changed method of detecting secure signalling channel (TLS) when allowing SRTP in a SIP call. More tolerant in the face of others failures.
Fixed OpenPhone call deflection on no answer.
Fixed SIP "Transfer" before call establishment, should use 302 response.
Fixed SIP call deflection, system being deflected would drop call.
Fixed minor issue with balloon text in OpenPhone not going away when call goes away.
