Subject: [PATCH 24/37] libperf: Add PERF_RECORD_SWITCH 'struct context_switch_event' to perf/event.h

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

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

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