[PATCH 18/47] perf session: Export a few functions for event processing

From: Arnaldo Carvalho de Melo
Date: Wed Aug 07 2013 - 17:23:26 EST

From: David Ahern <dsahern@xxxxxxxxx>

Allows kvm live mode to reuse the event processing and ordered samples
processing used by the perf-report path.

v2: removed flush_sample_queue as noticed by Jiri
