  Modified files:
    sys/dev/vinum        vinumconfig.c 
  Log:
  Change printf() calls to log() calls.
  
  Rename the VF_KERNELOP to VF_DISKCONFIG and checkkernel () to
  checkdiskconfig (), which better describes their function.
  
  Disable configuration updates if we have an error reading in the
  configuration.  This stops a "shoot-in-foot" problem where a mistake
  can cause the configuration to be obliterated.
  
  Tidy up some messages, which included superfluous \ns.
  
  Recognize RAID-5 configuration information even in the non-RAID-5
  version.  This fixes shoot-in-foot problems where starting the wrong
  version of vinum would kill RAID-5 plexes.
  
  Recognize drives that have been referenced, but for which no physical
  location is known.  This is part of a modification which will
  ultimately allow incrementally reading configurations.  Such drives
  will have a device name "unknown".
  
  New function return_drive_space () returns space to a drive.
  Previously this was part of free_sd ().
  
  give_sd_to_drive: don't do it if the subdisk needs more space than the
  drive has available.
  
  config_sd: if reading config from disk, accept plex offset, drive
  offset and length specs of -1 to indicate error conditions.
  
  parse_config: return ENOENT if the "read" command doesn't find any
  drives.
  
  remove_sd_entry: don't do it, even by force, if it's open.
  
  If the size of a striped or RAID-5 plex is not an integral multiple of
  the stripe size, trim the size until it is.
  
  reinstate update_volume_config, which had atrophied, to recalculate
  the size of a volume if a plex has shrunk due to stripe size
  considerations.
