Clean up the code to support 64-bit addressing in disks and
        files. This change is not enough for filesystems yet.

        type of "start" to grub_uint64_t.
        (setup): Change the types of KERNEL_SECTOR and FIRST_SECTOR to
        grub_disk_addr_t * and grub_disk_addr_t. Fix the format string in
        save_first_sector and save_blocklists. Use grub_le_to_cpu64 to
        convert addresses.

        * util/i386/pc/biosdisk.c (open_device): Change the type of SECTOR
        to grub_disk_addr_t.

        string.
