qemu-img info provides only pretty general information about an image. For any image format, there might be specific options which cannot be represented in a universal way; for instance, qcow2 provides the compatibility and lazy_refcount options whose values are certainly interesting but currently cannot be output by qemu-img info.
Therefore, this series adds an info-string field to ImageInfo resp. info_string to BlockDriverInfo which may be used by block drivers to hand an uninterpreted string to the user. It also adds support to qemu-img info and qemu-io -c info to dump that field's value.
