Add a new at_shutdown queue, SHUTDOWN_FINAL. This queue is run at splhigh() after any system dumps have completed. SHUTDOWN_POST_SYNC isn't quite late enough for disk controllers.

There are three shutdown queues, the first is run before the final filesystems
sync, the second is run after the sync, before the system disables all
interrupts, and the last queue is run with interrupts disabled just before
the system is reset or halted

is reversed to that of insertion.
