[PATCH 16/24] tools lib traceevent: Rename pevent_filter* APIs

["Tzvetomir Stoyanov (VMware)" <tz.stoyanov@gmail.com>]

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_FILTER_ERROR_BUFSZ, pevent_filter_alloc,
pevent_filter_add_filter_str, pevent_filter_match, pevent_filter_strerror,
pevent_event_filtered, pevent_filter_reset, pevent_filter_clear_trivial,
pevent_filter_free, pevent_filter_make_string, pevent_filter_remove_event,
pevent_filter_event_has_trivial, pevent_filter_copy, pevent_update_trivial,
pevent_filter_compare
