Log message:
Updated disklabel format to support larger disks and partitions. We
free room in struct partition by packing fragment size and
fragments/block more tighlty and use the resulting space to make
offset and size 48 bits.  For the disk part we use spare fields in
struct disklabel.  Kernel converts in-mem copy of the on-disk
label if needed, disklabel(8) writes new version.
We are careful to only change fields not used by bootloaders.
Conception of basic scheme by deraadt.
