Mitigate state fluctuations near the live edge of a DVR stream

[defagos]

As a user I want user interfaces to have a steady state when playing near the live edge. This is currently not the case as can be seen in the demo:

• The live button might fluctuate between red and gray states.
• The playback speed list might change once I have returned to the live edge at high speeds.

Acceptance criteria

• The aforementioned issues have been fixed.

Hints

This is likely similar to playback speed fluctuations mitigated in SRG Media Player. When nearing the live edge at speeds > 1 we should probably consider we are back at the live edge when the distance to the time range end is smaller than some distance d, small but large enough for the behavior to work over AirPlay.

Conversely, when moving away from the live edge at speeds < 1 we should probably consider we are away from the live edge when the distance to the time range is is larger than d+c.

This live edge criterium could probably be published and used not only to drive the ability to skip to the default position, but also to decide which speed range is supported for a DVR stream.
