Updates FMJ to r5 from the sourceforge SVN repository. This version uses a java.util.logging.Logger to log, and logs detailed statistics from the RTPSourceStream class. Changes MediaServiceImpl to always enable FMJ logging.

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. Corrects problems when: loading the same device twice (for the moment only for the same hostapi), a new plugged device is selected during a call or if the selected device is unchanged.

Allows the remote party to override payload type for the media we send to it. Payload types are no more overridden locally, and remote settings are used only for the media we sent to the that participant.

Renames a couple of methods upon request by Emil Ivov. Fixes an endless loop on hangup. Commits work in progress on sound notifications.

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.

Corrects media stream stats documentation and a null pointer exception which occurs when the media stream is closed.

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.

Adds the number of packets discarded by the FMJ packet queue to the "call info" window and to the logs at the end of a call.

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.

Adds more options to sound notifications and their config. Sound notifications now can use playback, notification or pc speaker device.

Adds FEC support for the SILK codec. Minor clean-ups in EncodingConfiguration and MediaConfigurationImpl.

Initialize EncodingConfiguration before postInitializeOnce, fixes exception MalformedURLException: Unknown protocol: portaudio when creating ZrtpFortunaEntropyGatherer.

Makes MediaServiceImpl#getDefaultDevice return non-null even if no formats are enabled for the device. Updates some of it's usages accordingly. This fixes a problem with SIP audio calls failing when all video formats are disabled.

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.

Adds support for the IETF Opus codec (patch by Boris Grozev). Fixes a problem that prevented Jitsi from using formats that are disabled by default (pach by Boris Grozev)

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.

Corrects writing DTMF payload (RFC4733) for RTP packets, when the RTP packet length is greater then the fixed header (i.e. with CSRC identifiers).
