[PATCH 28/33] libperf: Add PERF_RECORD_SAMPLE 'struct sample_event' to perf/event.h

[Arnaldo Carvalho de Melo]

From: Jiri Olsa <jolsa@xxxxxxxxxx>

Move the PERF_RECORD_SAMPLE event definition to libperf's event.h header
include.

In order to keep libperf simple, we switch 'u64/u32/u16/u8' types used
events to their generic '__u*' versions.
