Changes: 1. Removed _voiceEngineObserver boolean flag, because its value is equal to (_voiceEngineObserverPtr != NULL). 2. Removed WEBRTC_TRACE macro usage wherever it was unnecessary to log. Replaced its usage with LOG_F (new and preferred way to log messages) wherever it is useful to log. 3. Replaced asserts with CHECKs. Discussion: To make it easier to review the changes, I didn't reformat the code to make it compliant to the new coding standards. It is up for debate how much reformatting to do: the whole file/class or just the methods that I have touched. My vote - go for the whole class.
