tools lib traceevent, perf tools: Rename pevent alloc / free 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_alloc, pevent_free, pevent_event_info and pevent_func_resolver_t
