perf tools: Add trace-event object
Add trace-event object to keep together 'struct pevent' object with its
loaded plugins with following interface:
int trace_event__init(struct trace_event *t);
- Initalizes 'struct pevent' object and loads plugins for it
void trace_event__cleanup(struct trace_event *t);
- Cleanups both 'struct pevent' and plugins
