Three commits at my "for_hpa" branch (not derived from any old for_hpa

installer.  - Shao

    We will produce an error message if a user attempts
    to use an option we don't implement.

    libinstaller: Add --mbr, --active, and --force options

    In order to consolidate the installer option-parsing system,
    we add the --mbr (-m), --active (-a), and --force (-f)
    options from the DOS, Win32, and mtools installers to
    libinstaller.

    Since the -m and -a options are not currently valid for the
    Linux 'syslinux' and 'extlinux' installers, we add error
    messages to both of these.  The -f option is allowed but
    does nothing for them.
