336a6f070b Moved prototypes for devswitch functions from conf.c and driver sources 
to <machine/conf.h>.  conf.h was mechanically generated by
`grep ^d_ conf.c >conf.h'.  This accounts for part of its ugliness.  The
prototypes should be moved back to the driver sources when the functions
are staticalized.

b25431cbea Fix benign type mismatches in devsw functions. 82 out of 299 devsw 
functions were wrong.

8467ec16ea Change dsioctl() interface to allow DIOCSYNCSLICEINFO to update the caller's 
slice pointer and to print the device name in error messages.

121e99df24 (Sorry about prev. blank message - I realised I needed a change too late).

874da2b43f Escentially a rewrite by John Dyson. This is disgusting, and John agrees, 
but the whole thing is, so what the hell. :-) This version is expected to
work.

2269686ee1 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.

e11bf3ee66 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().

20aaa0b802 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.

2db3914936 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).

a9cb5cddf7 Warning: vn doesn't work just now. I havn't found out why. This commit 
just removes a couple of unused functions.

a867a90930 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.

0c17d10a45 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.
