tools lib traceevent: Rename pevent_data_ APIs

Browse Source 
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_data_lat_fmt, pevent_data_type, pevent_data_event_from_type,
pevent_data_pid, pevent_data_preempt_count, pevent_data_flags,
pevent_data_comm_from_pid, pevent_data_pid_from_comm, pevent_cmdline_pid
