tracing: move trace point formats to files in include/trace directory Impact: clean up To further facilitate the ease of adding trace points for developers, this patch creates include/trace/trace_events.h and include/trace/trace_event_types.h. The former file will hold the trace/<type>.h files and the latter will hold the trace/<type>_event_types.h files. To create new tracepoints and to have them automatically appear in the event tracer, a developer makes the trace/<type>.h file which includes <linux/tracepoint.h> and the trace/<type>_event_types.h file. The trace/<type>_event_types.h file will hold the TRACE_FORMAT macros. Then add the trace/<type>.h file to trace/trace_events.h, and add the trace/<type>_event_types.h to the trace_event_types.h file. No need to modify files elsewhere.
