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

        * util/i386/pc/grub-setup.c (struct boot_blocklist): Change the
        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.

        * partmap/gpt.c (gpt_partition_map_iterate): Fix the format
        string.

        * partmap/pc.c (pc_partition_map_iterate): Likewise.

        * partmap/amiga.c (amiga_partition_map_iterate): Cast RDSK.MAGIC
        to char *.

        * normal/script.c (grub_script_parse): Remove unused MEMFREE.

        * normal/parser.y (YYLTYPE_IS_TRIVIAL): New macro.

        * normal/lexer.c (grub_script_yyerror): Specify unused to LEX.

        * loader/i386/pc/multiboot.c (grub_multiboot_load_elf64): Cast -1
        to grub_off_t, to detect an error from grub_file_seek.
        (grub_multiboot_load_elf32): Likewise.

        * kern/misc.c (grub_strtoul): Use grub_strtoull. Return the
        maximum unsigned long value when an overflow is detected.
        (grub_strtoull): New function.
        (grub_divmod64): Likewise.
        (grub_lltoa): use grub_divmod64.

        grub_disk_addr_t.
        (grub_fs_blocklist_open): Increase P if P is not NULL to advance
        the pointer to next character. Use grub_strtoull instead of
        grub_strtoul.
        (grub_fs_blocklist_read): Change the types of SECTOR, OFFSET and
        SIZE to grub_disk_addr_t, grub_off_t and grub_size_t,
        respectively.

        return value is signed.
        (grub_file_seek): Change the type of OLD to grub_off_t. Do not
        test if OFFSET is less than zero, as OFFSET is unsigned now.

        * kern/disk.c (struct grub_disk_cache): Change the type of
        "sector" to grub_disk_addr_t.
        (grub_disk_cache_get_index): Change the type of SECTOR to
        grub_disk_addr_t. Calculate the hash with SECTOR casted to
        unsigned after shifting.

        grub_disk_addr_t.

        grub_disk_addr_t and grub_uint64_t, respectively.
        (grub_disk_read): Use an unsigned variable REAL_OFFSET for the
        body, as the value of OFFSET is tweaked by
        grub_disk_check_range. Change the types of START_SECTOR, LEN and
        POS to grub_disk_addr_t, grub_size_t and grub_size_t,
        respectively.
        (grub_disk_write): Use an unsigned variable REAL_OFFSET for the

        grub_size_t.

        * io/gzio.c (struct grub_gzio): Change the types of "data_offset"
        and "saved_offset" to grub_off_t.
