Mega update to the aac driver.

1.  Correctly handle commands initiated by the adapter.  These commands
    are defered to a kthread responsible for their processing, then are
    properly returned to the controller.
2.  Add/remove disk devices when notified by the card that a container was
    created/deleted/offline.
3.  Implement crashdump functionality.
4.  Support all ioctls needed for the management CLI to work.  The linux
    version of this app can be found at the Dell or HP website.  A native
    version will be forthcoming.
