Count partitions from 1 instead of 0 in the string representation
        of partitions. Still use 0-based internally.

        * partmap/sun.c (grub_sun_is_valid): A cosmetic change.
        (sun_partition_map_iterate): Use grub_partition_t instead of
        struct grub_partition *. Cast DESC->START_CYLINDER to
        grub_uint64_t after converting the endian.
        (sun_partition_map_probe): Subtract 1 for PARTNUM.
        (sun_partition_map_get_name): Add 1 to P->INDEX.

        * partmap/pc.c (grub_partition_parse): Subtract 1 for
        PCDATA->DOS_PART.
        (pc_partition_map_get_name): Add 1 into PCDATA->DOS_PART.

        * partmap/gpt.c (gpt_partition_map_iterate): Initialize PARTNO to
        zero instead of one.
        (gpt_partition_map_probe): Subtract 1 for PARTNUM.
        (gpt_partition_map_get_name): Add 1 into P->INDEX.

        of POS to unsigned.
        (apple_partition_map_probe): Subtract 1 for PARTNUM.
        (apple_partition_map_get_name): Add 1 into P->INDEX.

        * partmap/amiga.c (amiga_partition_map_iterate): Change the type
        of POS to unsigned.
        (amiga_partition_map_iterate): Cast NEXT to grub_off_t to
        calculate the offset of a partition.
        (amiga_partition_map_probe): Subtract 1 for PARTNUM.
        (amiga_partition_map_get_name): Add 1 into P->INDEX.

        * partmap/acorn.c (acorn_partition_map_find): Change the type of
        SECTOR to grub_disk_addr_t.
        (acorn_partition_map_iterate): Likewise.
        (acorn_partition_map_probe): Subtract 1 for PARTNUM.
        Change the type of SECTOR to grub_disk_addr_t. Declare P on the
        top.
        (acorn_partition_map_get_name): Add 1 into P->INDEX.

        * kern/i386/pc/init.c (make_install_device): Add 1 into
        GRUB_INSTALL_DOS_PART.

        * fs/iso9660.c (grub_iso9660_mount): Fixed a reversed
        conditional.
