Subject: [PATCH 20/37] libperf: Add PERF_RECORD_AUXTRACE 'struct auxtrace_event' to perf/event.h

From: Jiri Olsa <jolsa@...nel.org>

Move the PERF_RECORD_AUXTRACE event definition to libperf's event.h.

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