Mike Smith db82a982a7 Add a new sysctl node kern.shutdown, off which shutdown-related things
can be hung.

Add a tunable delay at the beginning of the SHUTDOWN_FINAL at_shutdown
queue, allowing time to settle before we launch into the list of things
that are expected to turn the system off.

Fix a bug in at_shutdown_pri() where the second insertion always put
the item in second position in the queue.
