sync with work by Greg Oster on NetBSD

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
