Subject: [PATCH 5/5] perf tools: Remove event types framework completely
Removing event types framework completely. The only remainder
(apart from few comments) is following enum:
enum perf_user_event_type {
...
PERF_RECORD_HEADER_EVENT_TYPE = 65, /* depreceated */
...
}
It's kept as depreciated, resulting in error when processed
in perf_session__process_user_event function.
