The JNI code for VoiceEngine is not maintained and VoiceEngine is being refactored. This is not a supported Java interface, use AppRTCDemo as a starting point instead. Also renames webrtc/libjingle_examples.gyp webrtc/webrtc_examples.gyp to replace the previous file (that only contained media_demo).
