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.

to char *.

maximum unsigned long value when an overflow is detected.

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.

respectively.
(grub_disk_write): Use an unsigned variable REAL_OFFSET for the
