Subject: [PATCH 1/5] perf session: Export queue_event function

Taking a lesson from perf-trace and bringing in control of event
processing to perf-kvm-stat-live: parse the sample to get access the
time leaving just the need to queue it to the ordered samples list.
For that the queue_event function needs to be exported.

Unexport perf_session__process_event.
