Fallback to the legacy VLC-proprietary "x-plgroup" for backward
compatibility with old VLC UDP streams.

npt's are double in live555 lib. We were loosing precision, and it avoids double->float->double conversions

Fix #6375

This fixes some problematic behaviour, when the user changed some settings
but has still not made a restart.

The default gain of 0.2 was way too low compared to other audio codecs.

This should fail safe, but it is still ugly.

This should be much cleaner than drawing ourselves inside the paintEvent
of the widget. Furthermore it is easier to fallback to the native slider
available in pre 2.0.
The use of a QStyle also fixes the clipping issue where the handle was
cropped while being at the start or the end of the slider.
