e10469fef8 Make md(4) and mdconfig(8) take over the role of vn(4) and vnconfig(8) 
entirely as previously advertised.

md(4) adopted all assets of vn(4) some time back and has proper devfs
support and cloning abilities to boot.

83da2a90ae 1) If mdconfig isn't given an action argument, it assumes detach. 
2) Running `mdconfig -l` without any attached devices results in
mdconfig printing "md0" to standard output.

3f6f92161c Remove "autounit" from settable options, it's the default unless you 
specify -u.

3b42f2f3bb Duh, the version of mdconfig.c I committed came from the wrong machine. 
Commit the right version, but without the -b option which is too evil
for the present.

Remove -b and preload from the manpage as well.

e06b153abe Add padding space and a version number to the md_ioctl structre for future 
extension.

Add ability to create a preload disk giving an address and a length
(suggested by imp)

Fix bug relating to very small md(4) devices.

Update md.c copyright to reflect the status of code copied from vn.c.

8f8def9e2c This is the first snapshot of the new all-singing-and-dancing md(4). 
Using the mdconfig(8) program you can now configure memory disks
on malloc(9), swap or a file/vnode.  preloaded md disks also work
as usual.

c2ef0b73df Improve cmdline parsing and messages. 
Add a rudimentary man-page.  (I'm no mdoc wizard, feel free to attack my
mistakes and blunders)

70d586c091 Preliminary scaffolding for the new integrated vn+md device driver. 
I decided to work on the md(4) driver and integrate the vn(4)
functionality into it mainly based on the name being more suitable.
Ideally 'vd' as in "virtual disk" would probably be the most logical
but our sound-master pointed out that this would cause uncontrollable
fits of giggles in the brits.  Another complication would the needed
changes to the ramdisk boot/root functionality.

The vn driver will stay around for some time after I complete this
merge for transition reasons, and I'll make it whine to people that
they should migrate to the md(4) driver for some time before it
dies.

The kernel part of the new md(4) driver will be committed after more
testing.
