  Log:
  Make bsd_disklabel_le_enc calculate the checksum and fill it in.
  (If there is a legitimate need to correctly encode and pack a
  disklabel with an invalid checksum custom tools can be built for
  that.)
  
  Make bsd_disklabel_le_dec() validate the magics, number of partitions
  (against a new parameter) and the checksum.
  
  Vastly simplify the logic of the GEOM::BSD class implementation:
  
  Let g_bsd_modify() always take a byte-stream label.
  
  This simplifies all users, except the ioctl's which now have to
  convert to a byte-stream first.  Their loss.
  
  g_bsd_modify() is called with topology held now, and it returns
  with it held.
  
  Always update the md5sum in g_bsd_modify(), otherwise the check
  is no use after the first modification of the label.  Make the
  MD5 over the bytestream version of the label.
  
  Move the rawoffset hack to g_bsd_modify() and remove all the
  inram/ondisk conversions.
  
  Don't configure hotspots in g_bsd_modify(), do it in taste instead,
  we do not support moving the label to a different location on the
  fly anyway.
  
  This passes all current regression tests.
