Takes another try at echo cancellation, uses a circular buffer to improve the latency (a teeny-weeny bit).

Other recent changes in earlier versions:

Allow remote candidate to be injected while ICE is running and enhance interoperability with Empathy client.

If we try to call an XMPP contact that does not support Jingle, print its address AND resource in error message.

Commits a patch provided by Bauersachs Ingo on the dev mailing list in the thread "Throwing an exception during SDP processing results in stray call window" which fails a call if parsing SDP throws an Exception.
Fix saving output device and add some debug prints.
Fix a problem with initial turning on the packet logging and update some config string resources.

Tunes the implementation of the blocking PortAudio stream interface op top of the non-blocking one, and the echo canellation.

Introduce Packet Logging Service with its configuration form and implementation for sip,jabber and rtp.
Remove a space in prop file that breaks loading bundles (introduced in previous commit).

When calling a contact that has multiple resources, choose the one that has the highest priority AND Jingle support.

Change the volume during a call while sliding (and not when the slider is released).

Display an error message when Jingle call failed if contact does not belong to our roster list, if it does not support Jingle.

When a call is on hold, disable only video, desktop streaming/sharing and DTMF buttons.
Fix local video display when we are the second to activate video in a XMPP call.

Fix a typo.
Fixes the 'Check for Updates' on Windows to start the setup as an update, not as a new install. The fix should be in effect after it is installed i.e. the setup may be started as a new install once but it should start as an update afterwards.

If ICE processing failed, fail the call, send a session-terminate to peer and display error message.
Attempt to fix disabled hold button when we have more than one call in the same time.
Fixes a memory (and thread) leak in AudioMixer.

Remove debug output.
Rebuilds the Mac OS X binary of the PortAudio support from its latest source/r7982.

Rebuilds the Windows x64 binary of the PortAudio support from its latest source/r7982.

Opens the PortAudio streams with a valid framesPerBuffer value in order to make it possible to use the pseudo-blocking PortAudio stream interface implemented in r7982.
Update check detecting wrong password on secure locations.

Implements the blocking PortAudio stream interface on top the non-blocking PortAudio stream interface in order to make it possible to use the DirectSound PortAudio implementation on Windows and to decrease the input/capture and output/playback latency.
Fixes a warning about isspace being implicitly declared.
