tools lib traceevent, perf tools: Rename pevent find 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_find_any_field, pevent_find_common_field,
pevent_find_event, pevent_find_field
