SCReAMv2: Visualize newly lost, recovered, and CE marked packet events

Calculates newly lost, recovered, and CE marked packet feedback events over a rolling window of one smoothed RTT (using ScreamV2::rtt()), as well as per individual feedback message (filtering out zero events).

Adds a new graph to analyze_bwe.cc displaying:
- Lost per smoothed RTT (continuous line)
- Recovered per smoothed RTT (continuous line)
- CE marked per smoothed RTT (continuous line)
- Lost per feedback (scatter points, non-zero only)
- Recovered per feedback (scatter points, non-zero only)
- CE marked per feedback (scatter points, non-zero only)

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 here for instructions on how to get started developing with the native code.
