Temporary fix for the issues with a NotRealizedError exception being thrown, and the camera being turned on in audio-only calls.

Commits the C source code of a fix of a memory corruption in the FFmpeg JNI library caused by the use of strdup instead of av_strdup.

Commits work in progress on updating to FFmpeg 1.0. The C source code of the FFmpeg JNI library is modified to use vanilla FFmpeg 1.0.

- Fixes a crash in Pa_StopStream. - Makes the switching of the audio device while in a call more thorough and resilient.

- 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.

- Prevents a NullPointerException in ice4j's Connector#stop() which appears quite often with unknown side effects.
- Prevents a NullPointerException in ToolsMenu related to the Jitsi VideoBridge menu item which causes of long chain of other exceptions and, eventually, prevents the application from completing its startup.
- Moves the C source code of JNI PortAudio library from Jitsi/net.java.sip.communicator to libjitsi/org.jitsi. Removes a couple of Java method and C function implementations each of which repeats three times. Fixes possible cases of leaving native callback threads which have been attached to the JVM in undetermined states.

Makes a minor API change. Pyload types are now overridden one by one in order to match the way we do this for the actual payload types

Fixes a discrepancy/inaccuracy in the RTP buffer length and minimum threshold of FMJ which leaves it vularable to even the tinies hiccups of the network. Rebuilds FMJ and libjitsi with debug information such as line numbers.

Updates library jni portaudio for Linux-32. Includes stdin.h and corrects warning about intptr_t in net_java_sip_communicator_impl_neomedia_portaudio_PortAudio.c (as suggested by Lyubomir Marinov).

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

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.

Prevents multiple dialing sounds from being played for multiple peers in a single call/telephony conference or for a peer who is being added to a telephony conference when there are other peers there already.

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.
