From: Namhyung Kim <namhyung....@lge.com> Now the event grouping viewing requires linking all member hists in a group to the leader's. Thus hists__output_resort should be called after linking all events in evlist.
Introduce symbol_conf.event_group flag to determine whether the feature is enabled or not.
