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.
* kern/fs.c (struct grub_fs_block): Change the type of "offset" to
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.
* kern/file.c (grub_file_read): Prevent an oveflow of LEN, as the
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

(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
body, as the value of OFFSET is tweaked by
grub_disk_check_range. Change the types of LEN and N to
grub_size_t.

and "saved_offset" to grub_off_t.

grub_size_t in "read".
All callers and references changed.
* include/grub/file.h (struct grub_file): Change the types of
