Subject: [PATCH 03/19] perf tools: Rename ordered_samples struct to ordered_events
Following up with ordered_samples rename for ordered_samples
and sample_queue structs to ordered_events and ordered_event
structs respectively.
Also changing flush_sample_queue function name to ordered_events_flush.
No functional change was intended.
