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

        grub_disk_addr_t.
        (grub_fs_blocklist_open): Increase P if P is not NULL to advance

        test if OFFSET is less than zero, as OFFSET is unsigned now.

        "sector" to grub_disk_addr_t.
        (grub_disk_cache_get_index): Change the type of SECTOR to
