qemu-img: Add --start-offset and --max-length to map
The mapping operation of large disks especially ones stored over a
long chain of QCOW2 files can take a long time to finish.
Additionally when mapping fails there was no way recover by
restarting the mapping from the failed location.
The new options, --start-offset and --max-length allows the user to
divide these type of map operations into shorter independent tasks.
