This permits one to setup a kernel able to automatically retrieve, during
boot, the raid configuration from disks previously used in a RAIDFrame
set. Moreover, one can define a raid set to contain a bootable partition
that will be mounted on / before the system has started.
A new RAID_AUTOCONFIG kernel option is used, in conjunction with the raid
pseudo-device, to activate the feature.
ok drahn@, deraadt@

- removed threadid stuff
- removed unused files
- general tidyup
- you can no longer configure the same unit twice (without
de-configuring first of course).
Again, this has only been tested locally on IDE disks. Further testing
and feedback would be appreciated.

Please note: This update has *only* been tested on i386 with IDE
disks. Could someone with a spare box please make sure all is OK with
SCSI and maybe other arches ? sparc testing will follow locally.
* remove rf_sys.h
* many changes to make it more stable
* some performance increases
* All raid threads now get their own kernel process and the calling
raidctl(8) program will show status progress through a meter.
* In theory FFS_SOFTUPDATES and RAIDframe will now work together - NOT
TESTED YET
See http://www.cs.usask.ca/staff/oster/raid.html
This updates include Greg's changes to Jan 4th 2000.
TODO:
* some odd behaviour when running raictl -c on an already config'ed
raid set - problem founf, fix being done
* progress meter is in raidctl(8) - seperate commit, but could do with
sync'ing with OpenBSD ftp version

* remove init call to rf_ConfigureEtimer() and rf_sys.c in which it is the
only function. update conf/files to reflect this.
* update sources to make sure _KERNEL is used not KERNEL
* change rf_etimer.h to protect macros an include of sys/kernel.h with
a check for _KERNEL - let raidctl compile again.

Please note that you *must* follow the upgrade instructions at
http://www.cs.usask.ca/staff/oster/clabel_upgrade.html
before installing the new raidctl and new kernel using this code.
