QMP: Disable monitor print functions

We still have handlers which will call monitor print functions
in several places. Usually to report errors.

If they do this when we are in control mode, we will be emitting
garbage to our clients.

To avoid this problem, this commit adds a way to disable those
functions. If any of them is called when in control mode, we will
emit a generic error.

Although this is far from the perfect solution, it guarantees
that only JSON is sent to Clients.
