    usr.sbin/makefs: Add HAMMER2 offline growfs support
    
    The offline growfs takes HAMMER2 specific "-o G" option.
    `image-file` argument is a valid HAMMER2 image file or block device.
    `directory` argument is unused, but needs to be a valid path or "--".
    
    e.g.
    $ makefs -t hammer2 -o G /dev/adx --
    $ makefs -t hammer2 -o G /path/to/hammer2.img --
    
    By default expands volume to image file or block device size.
    If -s option is specified, use that size.
    No shrink support in the same way hammer2(8) growfs doesn't.
