Update AvgCounter to have the ability to include last period metric for subsequent intervals without samples (e.g. for non-periodic updated stats).

Integrate AvgCounter to be used for BWE stats in call.

Fixes for stats regression in:
WebRTC.Call.EstimatedSendBitrateInKbps
WebRTC.Call.PacerBitrateInKbps

Example:
BWE for a 15 seconds long call (with intervals of 1 sec):
|300|400|500|600|600|600|600| 0 | 0 | 0 | 0 | 0 |800|800|800|  // 0 - network state down

Reported via OnNetworkChanged:
|300|400|500|600| x | x | x | 0 | x | x | x | x |800| x | x |  // x - empty interval, 0 -> pauses stats

Stats:
|300|400|500|600|600|600|600| - | - | - | - | - |800|800|800|  // x -> last value used (intervals during pause ignored)

AvgCounter uses the average of samples within an interval (interval length is 2 sec).

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. This page is maintained by the Google Chrome team.

Development

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