Summary [GStreamer] Buffering hysteresis and buffering improvements for Broadcom

The usage of a fixed buffering level to evaluate the need for buffering results in a too unstable behaviour on Broadcom platforms, with quick changes between states that may create stuttering when playing regular videos in stream mode (when not using on-disk buffering). Having some sort of hysteresis, with low/high watermark levels for buffering, would significantly improve the buffering logic and make it more stable. Also, on Broadcom Nexus devices, a big part of the media data is "hoarded" in the internal PlayPump subsystem, causing unrealisting buffer level readings when only the GstQueue2 element is queried for the buffering level. Any proposed solution must be compatible with the Quirks framework for custom Broadcom devices support. See: https://github.com/WebPlatformForEmbedded/WPEWebKit/issues/1309
