One little change and a fix

change.. 
You can now newfs /dev/rsd0 and mount it (/dev/sd0) without ever
disklabelling it. (its just a pile of blocks, why not have a FS on it?)
This is a byproduct of the fact that all slices appear identical,
whether or not they are subslices of subslices of subslices, or just a
whole raw disk. More interesting is the capacity to newfs and mount an
MBR slice (e.g. wd0s2) without going to the extra step of adding the
disklabel. Of course you need to disklabel to make a BOOTABLE part. :)

This is "Even more dangeroulsy dedicated mode"
It is more useful for the floppy where you can now do:
newfs /dev/rfd0 floppy3

Without the disklabel step. and still mount it.
This wan't the AIM but it's a byproduct of the aim of making all
disk abstractions identical.


fix:
Can now mount filesystems from floppies again without crashing the system.
(Thanks to Mike Smith for falling into that pit..)

This may be the version that gets checked in (Branch JULIAN_SLICES).
