[PATCH 21/35] tools lib traceevent: Rename pevent_find_* APIs

From: Arnaldo Carvalho de Melo
Date: Wed Aug 15 2018 - 11:08:13 EST


From: "Tzvetomir Stoyanov (VMware)" <tz.stoyanov@xxxxxxxxx>

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_find_function, pevent_find_function_address,
pevent_find_event_by_name, pevent_find_event_by_record
