PATCH v5 1/1 opensm/osmeventplugin: added new events to monitor SM

Adding new events that allow event plug-in to see when SM finishes heavy sweep and routing configuration, when it updates dump files, when it is no longer master, when SM port is down, and when SA DB is actually dumped at the end of light sweep:

OSM_EVENT_ID_HEAVY_SWEEP_DONE
OSM_EVENT_ID_UCAST_ROUTING_DONE
OSM_EVENT_ID_STATE_CHANGE
OSM_EVENT_ID_SA_DB_DUMPED

Signed-off-by Yevgeny Kliteynik <[email protected]>

Changes since v4:
- OSM_EVENT_ID_SA_DB_DUMPED was still reported during heavy sweep - removed.

Changes since v3:
- OSM_EVENT_ID_ENTERING_STANDBY and OSM_EVENT_ID_SM_PORT_DOWN replaced by OSM_EVENT_STATE_CHANGE
- OSM_EVENT_ID_SA_DB_DUMPED is not reported during heavy sweep, but only if SA DB was actually dumped at the end of light sweep
- fixed bug with OSM_EVENT_ID_MAX
