Dispatching & Queue Rewrite II:

Dispatching & Queue Rewrite II:

    - Rewrote wait code. It is now cleaner, more optimized and faster. All waiting
      functions are now clearly differentiated instead of sharing code. These functions
      are called up to a dozen times a second, so having dedicated code for each of
      them is a real boost in speed.
    - Fixed several queue issues, made a dedicated queue wait/wake function (you are not
      supposed to use KeWaitFor on a queue, and this is also a speed boost), and make it
      compatible with new wait code.
    - Optimized Work Queue code to be much smaller and better organized, by using an
      array instead of hard-coded multiple static variables. Also, add support for the
      real NT structures and implementation, paving the road for Dynamic Work Items, which
      also have timeouts, and deadlock dection + debug info.
    - Simplified PsBlockThread and made it compatible with wait code.
    - Added support for priority boosting when unwaiting a thread; will use later, as well
      as put proper boosting for dispatch objects.
    - Inlined all dispatcher lock functions and header initialization for speed.
    - Moved executive wait code into ob.
