    gpt, disklabel64 - Add storage expansion options
    
    * Add gpt expand directive.  For example 'gpt expand /dev/da0' will
      expand the gpt to fill /dev/da0.  This allows the gpt to be enlarged
      to fit a new, larger storage device or expanded storage and can be issued
      on a live gpt if desired.
    
    * Add disklabel64 -x and -xx features.  This expands the disklabel to
      fit the new enlarged slice that it resides in.  If -xx is specified,
      the last partition configured in the disklabel will also be enlarged.
    
    * And we already have 'hammer2 growfs <mountpt>' to grow a live hammer2
      filesystem to fit an enlarged partition.
