Big but mechanical.  It would be worth amending the commit message to
describe how you found all these spots (in case someone backporting
this patch has to redo the work over a different subset of files based
on what has changed since the two trees diverged).

Indeed a nicer idiom, where you are able to use it (whether by
self.assertEqual or by self.assert_qmp).
