    drm - Fix major stalls by fixing an improper taskqueue priority
    
    * drm was creating task queues with a LWKT priority of 0, which is
      lower than the priority of a running user thread.
    
    * Fix all cases where improper priorities are passed to
      taskqueue_start_threads().  This fixes major video stalls and glitches
      that occur when other things might be running on the system cpu-bound.
    
    * taskqueue_start_threads() now asserts if the priority passed to it is
      illegal.
