    fdisk(8): Fix a bug when reading >1TB slice sizes from a config file.
    
    The numerical parameters in configuration file lines were previously
    read into signed integers. This would cause a problem with a config
    file line like this (for a ~1.2TB slice):
    
    p 1 165 63 2491404993
    
    The length parameter (2491404993) for the slice would have exceeded
    INT_MAX (2147483647) and the slice would have been truncated to 1TB.
    
    Since the installer is using fdisk with a configuration file, it
    was previously not possible to use a whole >1TB disk from it (one
    had to work around it from the command line).
    
    To fix all this, read the numerical parameters in configuration file
    lines into a long long.
    
    Note that this change only affects the variable type into which the
    parameters read from the file are stored and not any on-disk structures.
    Also, checks at different places in fdisk(8) will of course still ensure
    that we don't ever go above 2TB.
