Marek Olšák	787ddadf73	util: add mesa_pin_threads environment variable that sets a static affinity mask ... This is required for deterministic benchmark results.

Marek Olšák	d230434ae3	mesa,gallium: move the thread scheduler to src/util ... The only change in behavior is that setting the affinity mask is skipped when it has no effect, which happens when the app thread hasn't been moved under a different L3 cache by the kernel (the sched_state variable tracks that). This improves performance because setting the affinity mask incurs measurable CPU overhead even if it has no effect.
