make fdisk grok extended partitions again. we have to keep track of the

absolute offset of the current mbr and its relative position. because:
the starting sector of the first mbr entry in an extended partition is relative
to the starting offset of the whole mbr itself. the starting offset of a new
extended partition is relative to the offset of the very first extended
partition.
