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.

Fixes issues with video conferencing such as the display of a non-focus participant's video to other non-focus participants and the stopping of the streaming between non-focus participants upon stopping of the streaming of the focus' local video.

- Works on removing the video of a video conference participant from display on the remaining non-focus participants. - Tries to fix a crash in PortAudio (often seen at the end of video conference calls).

Fixes an issue which would leak at least one Thread per call which would endlessly send out RTCP packets.

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.
