057b61aa1c Add "-n" argument, which causes mdconfig to simply print the unit 
number X, rather than mdX, making it easier to script tests that
use md devices but don't want to make assumptions about any existing
md use (such as in diskless environments).

Memory disks may be used for other purposes besides newfs(8), so it
isn't helpful to require the minimum size meet newfs(8)'s criteria.

045a8bbdf3 Introduce a force option, MD_FORCE, that instructs the driver to 
bypass some extra anti-foot-shooting measures.  Currently, its only
effect is to allow detaching a device while it's still open (e.g.,
mounted).  This is useful for testing how the system reacts to a disk
suddenly going away, which can happen with some removeable media.

At this point, the force option is only checked on detach, so it
would've been possible to allow the option to be passed with the
MDIOCDETACH operation.  This was not done to allow the possibility of
having the force flag influence other tests in the future, which may
not necessarily deal with detaching the device.

38354648cc Fail if -s isn't specified for an MD_MALLOC or MD_SWAP disk; the 
driver itself obviously won't configure such a disk, but the error
returned (EDOM) is more cryptic to the average user than it should be.

Also assert that the argument to -u is in fact a valid unit; don't
just accept any string to mean 0.

4728b0144a 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.
