This series adds the --backing-chain option for enumerating the backing file
chain. Given the topmost image it will print qemu-img info information for
each image file in the chain.
Special care needs to be taken when image files form an infinite loop. This is
very unusual, most like due to malicious image files. Nevertheless, qemu-img
must be robust against invalid inputs so we explicit check for this.

qemu-img: Add --backing-chain option to info command
qemu-img: Detect backing file chain infinite loops
qemu-iotests: Add 041 backing file chain infinite loop test
