resetconfig: don't log the "obliterated" message, the kernel does that 

for us.

	     Rebuild the (almost empty) /dev/vinum directory.

vinum_start:  remove superflous "read" parameter when starting with no
	      parameters.

vinum_stop:  without an argument, stop Vinum and remove the kld if
	     it's idle.

vinum_saveconfig: New command to save configuration.
