This doesn't cover the case where the value for the key is supposed
to be JSON null. You can either change this to something like
if ((t is not None and not isinstance(entry[k], t)) or
(t is None and entry[k] is not None)):
raise qmpSchemaException(...)
or, more simply, drop the check on t being None...

... and change the second member of the tuple to type(None) here.

Should we check whether query-qmp-schema and its output are in fact
present in the replies file? Or can we just assume that they're going
to be there?
