    vkernel - Unbreak 32-bit vkernel builds by fixing broken assertion
    
    * [ASSERT_]MP_LOCK_HELD() was not properly handling the new token
      t_count format.
    
    * Rename and document the functions a bit better.  Currently our
      more expansive token test for (shared or exclusive) is not
      a perfect test because we don't want to eat cpu time iterating
      the thread's token array to check for shared tokens.  So we just
      check for a shared count.
    
      Works well for assertions, wouldn't work very well for conditional
      acquisition (of a shared token).
    
    * Exclusive token tests are perfect.
