Søren Schmidt 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!
