For getting the reply I queried the newest and oldest QEMU using
test/qemucapsprobe. From the differences I only extracted the reply to the new
QMP command and discarded the rest. For all the versions below the one which
added support for the new option I used the output from the oldest QEMU release
and for those that support it I used the output from the newest one.
In order to make doubly sure the reply is where it is supposed to be (the
replies files are very forgiving) I added the property to all the replies files,
reran the tests again and fixed the order in replies files so that all the
versions are reporting the new capability. Then removed that one property.
After that I used test/qemucapsfixreplies to fix the reply IDs.
