85db7089ec Add support for creating/deleting ATA RAID's.
This completes the ATA RAID support, since all functions to manipulate
the RAID are accessible from FreeBSD, the BIOS on the ATA RAID cards
are only nessesary for booting.

I decided to allow for creation of ATA RAID's on any ATA controller, but
please keep in mind the restrictions on that. Due to the BIOS not
knowing what to do you can only boot from a RAID1 or the first disk
in a SPAN, if its not located on a "real" ATA RAID controller like
the Promise or Highpoint controllers.

6f87be981b Major update of the ATA RAID code, part 3:
Add code to properly detach/attach disks that are part of a RAID.

Mark a disk that is attached on an ATA channel belonging to a
RAID as a spare disk that can be used for rebuilding failed RAID1's.

Add support for rebuilding failed RAID1's.

Several fixes to the detach/attach code.

For replacing a disk in a failed RAID1 do the following:

Find the controller channel# of the failed disk.

Exec 'atacontrol detach <channel#>' to free the disk from the system.

Replace the failed disk with a new one of at least the same size.
If your have your disks in drawers/enclosures this can be done with
the system still running.

Exec 'atacontrol attach <channel#>' to add the disk to the system and
mark it as a valid spare for rebuild.

Exec 'atacontrol rebuild <array#>'

The system will rebuild the array on the fly, the array can still
be used during this, although with slower performance.

Please let me know of any problems with this!

e1605c6270 Major update of the ATA RAID code, part 2:
More cleanups of the RAID1 failure mode code.

Add functionality that writes the changed RAID config setup
back to the disks (in controller BIOS specific format), so
that a reboot will make the BIOS pick up the changed config.

4ad88f2ca4 Make LINT compile after fruitless attempts to get the authors
to fix their code.

ata stuff:
Change name of ar_attach to not colide with existing ar_attach in if_ar.c.
usb stuff:
Create a dummy function to satisfy a call to it when in DEBUG mode.

6ddce9039b Major update of the ATA RAID code, part 1:
Overhaul of the attach/detach code and structures, there were some nasty
bugs in the old implementation. This made it possible to collapse the
ATA/ATAPI device control structures into one generic structure.

A note here, the kernel is NOT ready for detach of active devices,
it fails all over in random places, but for inactive devices it works.
However for ATA RAID this works, since the RAID abstration layer
insulates the buggy^H^H^H^H^H^Hfragile device subsystem from the
physical disks.

Proberly detect the RAID's from the BIOS, and mark critical RAID1
arrays as such, but continue if there is enough of the mirror left
to do so.

Properly fail arrays on a live system. For RAID0 that means return EIO,
and for RAID1 it means continue on the still working part of the mirror
if possible, else return EIO.
If the state changes, log this to the console.

Allow for Promise & Highpoint controllers/arrays to coexist on the
same machine. It is not possible to distribute arrays over different
makes of controllers though.

If Promise SuperSwap enclosures are used, signal disk state on the
status LED on the front.

Misc fixes that I had lying around for various minor bugs.
