Tzvetomir Stoyanov (VMware) b843e9c3a2 tools lib traceevent: Rename pevent_register / unregister 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_register_print_function, pevent_unregister_print_function,
pevent_register_event_handler, pevent_unregister_event_handler,
pevent_register_function, pevent_register_trace_clock
