Add in a bunch of things to the mfi driver:

      - Linux ioctl support, with the other Linux changes MegaCli
	will run if you mount linprocfs & linsysfs then set
	sysctl compat.linux.osrelease=2.6.12 or similar.  This works
	on i386.  It should work on amd64 but not well tested yet.
	StoreLib may or may not work.  Remember to kldload mfi_linux.
      - Add in AEN (Async Event Notification) support so we can
	get messages from the firmware when something happens.
	Not all messages are in defined in event detail.  Use
	event_log to try to figure out what happened.
      - Try to implement something like SIGIO for StoreLib.  Since
	mrmonitor doesn't work right I can't fully test it.  StoreLib
	works best with the rh9 base.  In theory mrmonitor isn't
	needed due to native driver support of AEN :-)
Now we can configure and monitor the RAID better.
