Subject: [PATCH] qemublocktest: XMLjsonXML: Test formatting/parsing of modern
 JSON
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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.
