Summary0006503: Jobs system improvements
DescriptionRight now job system is rather limited in how many cores it can use (hardcoded with cvar).
The historical reason for that is parallel images loading, which should not use too many threads on HDD.
Time to improve core allocation for jobs system: use more cores in gameplay, use maximum cores during loading.

A big bunch of commits:
  r10669 Revised jobs system to use more cores (exact number determined automatically).
  r10670 Reimplemented parallel images loading with better parallelism.
  r10671 Fixes to producer-consumer queue.
  r10672 Added a way to conditionally use idScopedCriticalSection.
  r10673 Minor refactoring of idSoundCache::FindSound in preparation for parallel sounds loading.
  r10674 Implemented parallel loading of sound samples.
  r10675 Yet another EAS loading optimization.
  r10676 Great overhaul of mission load progress bar.

So the basic points here are:
1) Automatically use all physical cores during gameplay, all logical cores during loading/offline.
2) Better parallel loading of images.
3) Parallel loading of sound samples.
4) Better progress bar.
5) Further optimized EAS loading for maps with elevators.

Perhaps in some distant future I'll do parallel loading of models too.
Then all three "big" type of assets would be loaded in parallel =)
But not now.
