MXS-1848 Implement createInstance() and destroyInstance()

Browse Source 
CreateInstance() (renamed from initMonitor()) and destroyInstance()
(renamed from finishMonitor()) have now tentatively been
implemented for all monitors.

Next step is to

1) change the prototype of startMonitor() to

       bool (*startMonitor)(MXS_SPECIFIC_MONITOR*,
                            const MXS_MONITOR_PARAMETER*);

   and assume that mon->handle will always contain the
   instance,
2) not delete any data in stopMonitor(),
3) add monitorCreateAll() that calls createInstance() for all
   monitors (and call that in main()), and
4) add monitorDestroyAll() that calls destroyInstance() for
   all monitors (and call that in main()).
