Tzvetomir Stoyanov 69769ce159 perf tools, tools lib traceevent: Rename "pevent" member of struct tep_event to "tep"
The member "pevent" of the struct tep_event is renamed to "tep". This
makes the struct consistent with the chosen naming convention:

  tep (trace event parser), instead of the old pevent.
