Improves stereo/mono audio support on Android.

Fixes some issues related to calling WebRtcAudioManager.setStereoOutput(true)
and WebRtcAudioManager.setStereoInput(true) and ensures that the ADM reports
correct values related to stereo support given these settings.

Also makes it more clear that the OpenSLES audio implementation does not support
stereo (we now fail in Init()).

To summarize: this change ensures that the user can ask for stereo input
and/or stereo output audio on Android in combination with the Java based
audio layer. By default (if no WebRtcAudioManager.setStereoXXX() APIs are called), mono will be used.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.

Development

See http://www.webrtc.org/native-code/development for instructions on how to get started developing with the native code.
