Use single FrameBufferController in VP8, created by a factory.

This CL paves the way to making FrameBufferController injectable.

LibvpxVp8Encoder can manage multiple streams. Prior to this CL,
each stream had its own frame buffer controller, all of them held
in a vector by LibvpxVp8Encoder. This complicated the code and
produced some code duplication (cf. SetupTemporalLayers).

This CL:
1. Replaces CreateVp8TemporalLayers() by a factory. (Later CLs
   will make this factory injectable.)
2. Makes LibvpxVp8Encoder use a single controller. This single
   controller will, in the case of multiple streams, delegate
   its work to multiple controllers, but that fact is not visible
   to LibvpxVp8Encoder.

This CL also squashes CL #126046 (Send notifications of RTT and
PLR changes to Vp8FrameBufferController) into it.

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.

Authoritative list of directories that contain the native API header files.
