  Log:
  Add the following to the taskqueue api:
  
  taskqueue_start_threads(struct taskqueue **, int count, int pri,
                          const char *name, ...);
  
  This allows the creation of 1 or more threads that will service a single
  taskqueue.  Also rework the taskqueue_create() API to remove the API change
  that was introduced a while back.  Creating a taskqueue doesn't rely on
  the presence of a process structure, and the proc mechanics are much better
  encapsulated in taskqueue_start_threads().  Also clean up the
  taskqueue_terminate() and taskqueue_free() functions to safely drain
  pending tasks and remove all associated threads.
  
  The TASKQUEUE_DEFINE and TASKQUEUE_DEFINE_THREAD macros have been changed
  to use the new API, but drivers compiled against the old definitions will
  still work.  Thus, recompiling drivers is not a strict requirement.
