A free Windows-compatible Operating System - mirrored from GitHub

* Do not pollute the kernel with 10 real-time threads and 5 high-priority threads in order to manage work items. Work threads are very-low priority (< 7) and should never pre-empt userthreads like they do now. 1 priority 7, 5 priority 5 and 3 priority 4 threads are now properly created.
* Implement a worker thread balance set manager. On SMP systems, it is able to determine when a new thread should be allocate to execute on a free CPU. On both UP and MP, it is also able to detect if a work queue has deadlocked, and will allocate new dynamic threads to unfreeze the queue.
* Add check for threads returning with APC disabled, and re-enable APCs if this happend. This hack is used in NT for broken drivers.
* Lots of code changes to support dynamic threads, which:
- Can terminate.
- Use a 10 minute timeout on the kernel queue.
* Add skeleton code for swapping worker thread stacks as well as worker thread shutdown (not yet implemented).
* Add WORKER_INVALID bugcheck definition.
* These changes seem to make ROS a lot more responsive.
- NDK:
* Make more compatible with MS IFS
* Fix EX_WORK_QUEUE definition.
* Fix ETHREAD offsets.
* Fix RtlIsNameLegalDOS8Dot3 definition.
* Move splay tree defines to IFS.
