First approach to remove parts of the heavy load done for encoding, and preparation for sending, from native audio thread to separate task queue. With this change we will give the native input audio thread more time to "relax" between successive audio captures. Separate profiling done on Android has verified that the change works well; the load is now redistributed and the load of the native AudioRecordThread is reduced. Similar conclusions should be valid for all other OS:es as well.
