We decided that use of qemu-img would not be possible for this case. I'm
thus re-sending the patch with fixes to docs and the ISO image format
probe.
This approach is the simplest and most straightforward and deals with
most cases. Specifically we don't have to fix half of blockjob code by
doing this as opposed if we wanted to have qemu open the image itself by
looking into the overlay's metadata.

qemu: domain: Convert detected 'iso' image format into 'raw'
virStorageFileGetMetadataRecurse: Allow format probing under special
circumstances
kbase: backing_chains: Clarify some aspects of image probing
