The test was invoking the JSON formatter with the 'legacy' flag thus
formatting bunch of obsolete JSON blockdev definitions. We also should
test the modern ones. Add a boolean and re-run all the tests in both
cases.
Additionally for any modern invocation we should also validate that the
output conforms to the QAPI schema.

We need the "$(space)" variable to contain a single whitespace
character. We do this by assigning and then appending an empty

* WARNING: Backward-incompatibility!
Previously appending using '+=' to an empty variable would
result in a value starting with a space. Now the initial
space is only added if the variable already contains some
value. Similarly, appending an empty string does not
add a trailing space.

oVirt used a quirk in the pre-blockdev semantics of drive-mirror which
opened the backing chain of the mirror destination only once
'block-job-complete' was called.
Our introduction of blockdev made qemu open the backing chain images
right at the start of the job. This broke oVirt's usage of this API
because they copy the data into the backing chain during the time the
block copy job is running.
Re-introduce late open of the backing chain if qemu allows us to use
blockdev-snapshot on write-only nodes as it can be used to install the
backing chain even for an existing image now.
