[PATCH 03/35] perf ordered_events: Add ordered_events__last_flush_time()

[Adrian Hunter]

Allow callers to get the ordered_events last flush timestamp.

This is needed in perf inject to obey finished-round ordering when
injecting additional events (e.g. from a guest perf.data file) with
timestamps. Any additional events that have timestamps before the last
flush time must be injected before the corresponding FINISHED_ROUND event.
