* util/i386/pc/grub-install.in: If the drive is LVM or RAID, prepend
        it in prefix.

        * util/i386/pc/grub-setup.c (main): Don't handle prefix at all.  Set
        `must_embed' to 1 when root_dev is a RAID device.  When dest_dev is
        a RAID device, run setup() for all members independently on whether
        LVM abstraction is being used.
        (setup): Don't handle prefix at all; let grub-mkimage take care of it.
        If grub-mkimage has set `*install_dos_part == -2', don't override this
        value.
        Perform *install_dos_part adjustments independently on whether
        we're embedding or not.
        Clarify error message when image is too big for embedding.
        Remove duplicate *install_dos_part stanza.
