Keep track of installed number of probes to shortcut emission. Allow NULL callbacks, this is useful for blocking probes. Improve probe selection based on the mask, an empty mask for the data or the scheduling flags equals that all probes match. Add some more debug info. Don't check the flushing flag in the probe callback handler, this needs to be done before calling the handler. Fix blocking probes. Fix unit tests
