Changes needed for android merge. Exposing several bundle contexts. Some public constants. Changes in sound notifications to use String as resource uri, and obtaining resource input stream and stream format info from AudioSystem, so it can be overridden in different implementations.

Changes the default priority of Opus in the configuration, it's now on top. Removes the DVI4 codec formats, since they are not supported.

Refactors the way specific Codec instances are accessed in MediaStreamImpl. Passes "format parameters" received via SDP/Jingle to codecs, which can handle them (Opus).

- Removes the DirectSound support from PortAudio in order to prevent issues with bad audio quality.
- Attempts to recognize USB PortAudio devices on Windows as such, ignores the virtual Microsoft Sound Mapper devices to avoid user confusion. Contributed by Vincent Lucas.

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.

Moves Constants to the serivce package so that it would be accessible for other packages that need to access a PT name

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

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.

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 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.
