Add function vinum_mv, which moves subdisks to different drives. This
function just does the low-level configuration changes; the resultant
subdisk is stale if it previously had any contents, otherwise it is
empty (i.e. in need of initializing if it's RAID-5). We still need to
handle getting the contents moved over, but the current version will
suffice to migrate subdisks from a disk which has failed.

vinum_info: Change format of device numbers so that they fit in the
column (ignore high-order minor number bits, which aren't really of
much interest).
vinum_start: bzero the statinfo.dinfo struct. The lack of this was
causing sporadic failures of the start command.
Add body of vinum_checkparity command.
vinum_init(): Change name of variable plexindex to objindex, which
better describes its purpose.
initsd(): Add a second parameter to determine whether it should wait
for completion or not. This allows it to DTRT when called
with the -w flag either directly or via initplex().
Add 'setstate' command (function vinum_setstate ()) to implement the
VINUM_SETSTATE_FORCE ioctl for diddling individual object states.
This is a repair tool which can also be used for panicing the system.
Use with utmost care if at all.
Add unimplemented commands 'checkparity' and 'rebuildparity'. Watch

Add function definition for readpol command.

process, effectively kill off plex-bound subdisk device numbers.
