Ship ability to opt-in to VP9/AV1 simulcast (re-land).
This makes "WebRTC-AllowDisablingLegacyScalability" enabled-by-default,
meaning any app can opt-in to spec-compliant simulcast when
scalabilityMode is specified.
The opt-in criteria is also made more restricitve: you now have to
specify both scalabilityMode and scaleResolutionDownBy to get simulcast,
otherwise you continue to get legacy "single stream" path.
The reason for this is not to cause any surprises in use cases like
[{scalabilityMode:"L1T1", active:true}, {active:false}, {active:false}]
In cases like this where scaleResolutionDownBy is not specified, it
defaults to 4:2:1 if simulcast is used but the legacy path caps it to
one stream, meaning full resolution. By restricing simulcast only to
cases that set scaleResolutionDownBy, we remove the risk of an app
getting a different resolution than expected due to opt-in.

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