This CL introduces a new org.webrtc.VideoRenderer.Callbacks implementation called SurfaceViewRenderer that renders each video stream in its own SurfaceView. AppRTCDemo is updated to use this new rendering. This CL also does the following changes: * Make the VideoRenderer.Callbacks interface asynchronous and require that renderFrameDone() is called for every renderFrame(). In JNI, this is implemented with cricket::VideoFrame::Copy()/delete. * Make public static helper functions: convertScalingTypeToVisibleFraction(), getDisplaySize(), and getTextureMatrix(). * Introduces new helper functions surfaceWidth()/surfaceHeight() in EGlBase that allows to query the surface size. * Introduce PercentFrameLayout that implements the percentage layout that is used by AppRTCDemo.
