tools lib traceevent: Rename various pevent APIs 

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "pevent_". This changes
APIs: pevent_reset_function_resolver, pevent_strerror, pevent_list_events,
pevent_event_common_fields, pevent_event_fields, pevent_ref, pevent_unref
