  Log:
  Rewrite minor number decoding.  Now we have only three types of
  object: subdisks, plexes and volumes.  The encoding for plexes and
  subdisks no longer reflects the object to which they belong.  The
  super devices are high-order volume numbers.  This gives vastly more
  potential volumes (4 million instead of 256).
  
  As a result of the minor number changes, split out the superdevice
  handling into a separate function, vinum_super_ioctl.  This was most
  of the code of vinumioctl.
  
  attachobject: Improve error checking.
