Improves device selection via portaudio for MacOSX (hostapi coreaudio): adds the possibility to get the device transport type (USB, bluetooth, etc.) and an unique identifier.

Improves sound device selection: automatically switches to new plugged device, remember user preferences in a list.

Commits work in progress on refactorying the call-related user interface for the purposes of audio and video telephony conferencing over single or multiple protocols and Jitsi VideoBridge.

Implements a mechanism that allows JMF Controls registered in the  codec implementations to be accessed in MediaStream. Adds a FECDecoderControl interface and uses it to collect FEC statistics in MediaStreamStatsImpl. Adds a "Packets decoded with FEC" line in the call info window.

Changes the EncodingConfiguration instance stored in MediaServiceImpl to one which contains global settings. Changes the names of some methods in EncodingConfiguration and MediaService to make their meaning more clear. Adds storeProperties() methods to EncodingConfiguration, makes EncodingsPanel use them.

Applies a patch from Boris Grozev that allows setting different codec configurations to different accounts. It is now possible to set entirely different codec preference for every account.

Fixes issues with video conferencing such as a failure of the local video to be displayed and a limitation of the conference focus with respect to requiring it to capture video as well.

Fixes a failure to keep the aspect ratio of the video when switching to full screen. Attempts to remedy a multi-video display when switching between camera and desktop streaming. Tries to fix a crash in the QTKit video capture on Mac OS X. Works on addressing a unnecessary remaining of the camera on Mac OS X open.

Updates the detection of a remote desktop sharing call via the new Controls of imgstreaming.DataSource, in order to display a desktop icon as the local visual.

Commits an initial version of the libjitsi library which should be fully functional with respect to neomedia/MediaService and should be usable with and without OSGi.
