block-qcow2: keep highest allocated byte (Uri Lublin)
We want to know the highest written offset for qcow2 images.
This gives a pretty good (and easy to calculate) estimation to how
much more allocation can be done for the block device.
It can be usefull for allocating more diskspace for that image
(if possible, e.g. lvm) before we run out-of-disk-space
