Adds an Opus configuration form and changes the default Opus settings. Updates the Opus JNI binaries. Notifies encoders that implement PacketLossAwareEncoder (Opus and SILK) of packet loss information received via RTCP.

Replaces the Opus libraries with ones linked against a lower version of glibc (so that they run on debian, for example)

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)

Re-applies the ideas of r9718 with a refined implementation on the PulseAudio Renderer in order to reflect changes to the user's choice with respect to the default playback device while in a call.

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.
