- Clean up kernel32\thread.c and fix some bugs.

Browse source 
- Implement KeSetDisableBoostThread.
- Temporarily disable SEH/validation in NtQuery/SetProcess/ThreadInformation routines since it was making all calls fail.
- Fix bugs when using ThreadPriority, ThreadBasePriority, ThreadAffinityMask. Parameters are now validated properly, and affinity masked with the process.
- Implement ThreadSetIdealProcessor and ThreadPriorityBoost case.
- Implement ThreadZeroTlsCell case. TLS should now work properly.
- Make kernel32_winetest for threads usable.
- Update Kernel Fun.
