Fix FrameConfigs used for VP8 with four temporal layers. sync flag should only be true if: * temporal layer > 0 * frame predics _only_ from tl0 (last) Furthermore, flags should not predict from a buffer unless it has been previously updated in the current iteration for the pattern. I also added an experiment with an alternative pattern for a three layer setup, where loose some efficieny by halving the pattern but gain a little bit by updating arf for the top layer. The theory is that this will cause fewer frame drops since we don't have as much dependency on previous frames in the upper layer (which might not be retransmitted).

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