iotests: Add test for potentially damaging repairs There are certain cases where repairing a qcow2 image might actually damage it further (or rather, where repairing it has in fact damaged it further with the old qcow2 check implementation). This should not happen, so add a test for these cases. Furthermore, the repair function now repairs refblocks beyond the image end by resizing the image accordingly. Add several tests for this as well. Signed-off-by: Max Reitz <mreitz@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
