Reduce implementations of CallStatsObserver by 2.

Both of these implementations are added as observers by
VideoReceiveStream, which is also an observer.

Instead, VideoReceiveStream now forward the necessary information
when the stats are updated as is already done for |frame_buffer_|.

Fewer observers registered, simplifies the code a little bit,
reduces synchronization when registering/unregistering observers
and reduces the set of existing implementations.

(I'm changing call_stats.* a little bit, so this is a by-the-way change)

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.
