ecd1c51f92 Do some small cleanups to comments and remove AACQ_COMPLETE definitions since
the completion queue is long-gone.

36e0bf6e9c 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.

fb0c27d7e2 Put the linux compat ioctl interface on death row. Add FreeBSD
definitions of all of the ioctls, plus round out all ioctl definitions to
match what exists for linux.  Allow ioctls to be called through either the
native or linux interface, though no apps exist (yet) that can take
advantage of native calling.

0b94a66e3f Major bugfix and minor update. This should resolve the current issues
with the driver locking up under load.

 - Restructure so that we use a static pool of commands/FIBs, rather than
   allocating them in clusters.  The cluster allocation just made things
   more complicated, and allowed us to waste more memory in peak load
   situations.
 - Make queueing macros more like my other drivers.  This adds queue stats
   for free.  Add some debugging to take advantage of this.
 - Reimplement the periodic timeout scan.  Kick the interrupt handler
   and the start routine every scan as well, just to be safe.  Track busy
   commands properly.
 - Bring resource cleanup into line with resource allocation.  We should
   now clean up correctly after a failed probe/unload/etc.
 - Try to start new commands when old ones are completed.  We weren't doing
   this before, which could lead to deadlock when the controller was full.
 - Don't try to build a new command if we have found a deferred command.
   This could cause us to lose the deferred command.
 - Use diskerr() to report I/O errors.
 - Don't bail if the AdapterInfo structure is the wrong size.  Some variation
   seems to be normal.  We need to improve our handing of 2.x firmware sets.
 - Improve some comments in an attempt to try to make things clearer.
 - Restructure to avoid some warnings.
