Add a new --limits option to 'qemu-img info' that displays the block limits for the image and all of its children, making the information more accessible for human users than in QMP. This option is not enabled by default because it can be a lot of output that isn't usually relevant if you're not specifically trying to diagnose some I/O problem. This makes the same information automatically also available in HMP 'info block -v'.
