A substantial change to the way this works. Not the "TEST_LABELING" is
...
a option you can turn on and of on the fly, as is debugging.

Fake the geometry to be 32 sectors * 64 heads * (vn->sc_size / 2048)
...
cylinders instead of vn->sc_size * 1 * 1.
Remove unnecessary tests of the unit numbern vnioctl().

Thanks Ollivier.

Less bogus allocation of softc to avoid races.
...
Thanks for the hint David!

Remove the #error that temporarily stopped this from supporting slices and
...
labels.
Please test the slice/label features:
cd /dev; sh MAKEDEV svn0
cd /var/tmp; dd if=/dev/zero of=vnfile bs=8192 count=1024
vnconfig -c /dev/rvn0 /var/tmp/vnfile
fdisk /dev/rvn0 # invent a geometry, create one BSD partition
disklabel -r -w vn0 floppy # a convenient (bogus) label
disklabel -e vn0 # edit label to match device
newfs /dev/rvn0a
mount /dev/vn0a /mnt
...
The steps after the fdisk could name the device vn0s1 instead of vn0.

Temporarily stop this compiling if the option TEST_LABELLING is defined
...
so that new slice support code can be installed without risk of
corrupting vn devices (if any).

Warning: vn doesn't work just now. I havn't found out why. This commit
...
just removes a couple of unused functions.

Continue implementing disk slices and labels for the vn driver. Everything
...
is supposed to work except "media removal" (shutting down the vn driver)
while some partitions are open.
Fix some errnos: return ENOTTY, not ENXIO for unknown ioctls; return
ENODEV, not ENXIO for the unsupported dump operation.

Implement disk slices and labels for the vn driver. This is intended mainly
...
for testing and is only enabled if TEST_LABELLING is defined. It won't
actually work until DOS goop is removed from ufs_disksubr.c.

Avoid a panic if vn is configured as swapdev. Seems to work fine.
