o enable shutdown of taskqueue threads; the thread servicing the queue checks

  a new entry in the taskqueue struct each time it wakes up to see if it
  should terminate
o adjust TASKQUEUE_DEFINE_THREAD & co. to record the thread/proc identity for
  the shutdown rendezvous
o replace wakeup after adding a task to a queue with wakeup_one; this helps
  queues where multiple threads are used to service tasks (e.g. acpi)
o remove NULL check of tq_enqueue method; it should never be NULL
