ZeroHz: Repeat refresh frame requests until a frame is received.

When MediaStreamVideoSource::RequestRefreshFrame is called, the
capturer most often emits a refresh frame. Due to various
conditions such as for example timing of prior delivery,
these frames can be dropped at various places in the input
pipeline into WebRTC.

This change ensures the frame cadence adapter repeatedly
requests refresh frames at max fps frequency until one is
received, in which case the requests cease.

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
