* include/grub/ntfs.h (struct grub_ntfs_bpb): Rename `serial_number' to
        `num_serial' (for consistency with other variables).
        (struct grub_ntfs_data): Add `uuid' member.
        * fs/ntfs.c (grub_ntfs_mount): Initialize `data->uuid'.
        (grub_ntfs_uuid): New function.
        (grub_ntfs_fs): Reference grub_ntfs_uuid() in `uuid' struct member.
