[08/10] perf tools, tools lib traceevent: Rename "pevent" member of struct tep_event to "tep"

Commit Message

Tzvetomir Stoyanov April 5, 2019, 2:03 p.m. UTC

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.
