Kevin Wolf f62f08ab7a iotests: Test external snapshot with VM state
This tests creating an external snapshot with VM state (which results in
an active overlay over an inactive backing file, which is also the root
node of an inactive BlockBackend), re-activating the images and
performing some operations to test that the re-activation worked as
intended.
