    sbin/newfs_hammer2: Add newfs(8) -s option equivalent option
    
    Very useful for testing, file backed volume, etc.
    The difference vs newfs(8) is newfs_hammer2(8) takes filesystem
    size in bytes, using the same format as -b or -r options.
    
    The volume size is deducted from the value (in argv[i] order,
    where argc is number of volumes), and if the value reaches zero
    while there are remaining volumes, the program fails.
    
    Since -s option requires 1GiB (level1 size) or larger,
    the failure mentioned above happens only for multi-volumes.
