Updates fmj to the latest and greatest version that allows to override the default RTCP report creation algorithm and that includes an RTCP packet parser

Protects against JVM crash when closed SCTP socket is used by checking for null pointer and throwing IOException. Adds unit tests for SCTP wrapper.

Cleans up the background Threads associated with TURN candidates more explicitly/aggressively/thoroughly in an attempt to mitigate a leak of such reported by Enrico Marocco.

Updates fmj.jar to r48 (Runs the SSRCCacheCleaner every 5 seconds (and not only on reception of RTCP packets).

Uses UTF-8 instead of ASCII in Core Audio on OS X in order to potentially resolve issues with non-ASCII characters. (The solution is unlikely to be complete though because of the mixes usage of original UTF-8, modified UTF-8 and strlen.)

Fixes an audio quality degradation observed with Core Audio on OS X when the Audio tab in Preferences is open during a call.

Fixes a case which may lead to ignoring non-distinguishing but important format parameters/SDP fmpt such as H.264 sprop-parameter-sets.

Updates AEC for CoreAudio using webrtc library, recompiled with latest webrtc, was crashing when running from source with unresolved reference "___sincos_stret". Adds some basic instructions for compiling.

Updates fmj.jar to r40 (Fakes a TimeoutEvent when a ReceiveStream is replaced with a PassiveSSRCInfo (e.g. when an RTCP Receiver Report is received, instead of a Sender Report, for the ReceiveStream).).

Fixes a deadlock in the ICE implementation between Agent.free() and StunClientTransaction observed in Jitsi Videobridge.

Fixes an issue with Packet Loss Concealment (PLC) which could cause muting in Jitsi Videobridge conferences to 'repeat' after unmuting.

Uses a single Thread per StunStack to expire StunServerTransactions in order to reduce the total number of utilized Threads.

net.java.sip.communicator to the package org.jitsi.

Updates jnwincoreaudio.dll in order to comply with the package change for CoreAudioDevice, MacCoreAudioDevice and WebrtcAec to src.org.jitsi.impl.neomedia.device package.

Corrects Coreaudio endless loop when CoreAudio daemon underruns. Corrects freeing resources synchronization problem. Corrects AEC memory leak.
