perf tools: Add trace-event object

Browse Source 
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
