Reason for revert:
Broke webrtc_perf_tests on bots.

Original issue's description:
> Make overuse estimator one dimensional.
>
> This drops the payload size difference dimension of the Kalman filter,
> which doesn't improve the quality of the estimation when pacing packets
> on the send-side.

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.
