Hi,

support to qcow2.
Please refer to the cover letter of the first version for a full

https://lists.gnu.org/archive/html/qemu-block/2019-10/msg00983.html
This version is rebased on top of the latest master (f2a1cf9180),
fixes the relevant conflicts (particularly after df373fb0a3) and
updates the test expectations.
