tools lib traceevent: Rename pevent field 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_free_format, pevent_free_format_field, pevent_get_field_raw,
pevent_get_field_val, pevent_get_common_field_val, pevent_get_any_field_val
