Conflicts:
	lib/native/mac/libjnmaccoreaudio.jnilib - take theirs
	src/native/build.xml - accept their changes
	src/native/macosx/coreaudio/device.c - keep our fixes (but fix up changed function names)
	src/org/jitsi/impl/neomedia/device/WebrtcAec.java - accept their deletion
	src/org/jitsi/impl/neomedia/jmfext/media/renderer/audio/MacCoreaudioRenderer.java - keep our earlier fix; transfer our new log to their block for later conflict.
Rebuilt (static) libjnwebrtc libraries.
Built from source (http://webrtc.googlecode.com/svn/trunk at revision: 5860) using "ant webrtc-aec -Dwebrtc.src=/Users/tim/code/webrtc".
Committing as we don't want to have to rebuild ourselves every time.
Mac core audio fix - missed when fixing up merge conflicts.
Updated maccoreaudio library (rebuilt against newer webrtc libraries).
Merge branch 'master' into maccoreaudio
Take BlueJimp's version of libjnmaccoreaudio. (Matches what we have in AccessionDesktop).
Merge branch 'master' into maccoreaudio
Rebuilds the JNI library jnmaccoreaudio on and targeting OS X 10.7.
Fix demon wasps.  We had a loop that span waiting for the native audio system to start reading off the data.  Sadly we applied gain each time round the loop.  As a result, the audio would at times be overly loud (and clipped) or silent.
