Kai Krakow addfe1fbc0 scheduler: Add heuristics and option to force on/off

This commit adds a simple heuristic to auto detect whether to use
SCHED_ISO or not. It does this by looking at the number of cores:

According to some reports by users of SCHED_ISO and an explanation by
Con Kolivas, games running busy loops and running on too few cores might
start fighting with scheduling of the graphic driver, leading to
priority inversion. This results in actually lower performance.

So let's only enable SCHED_ISO on at least four cores.

The user can still force SCHED_ISO on or off by setting the
configuration value. All other values (or none) will apply heuristics.
