tools lib traceevent: traceevent API cleanup
In order to make libtraceevent into a proper library, its API should be
straightforward. This patch hides few API functions, intended for
internal usage only:
tep_free_event(), tep_free_format_field(), __tep_data2host2(),
__tep_data2host4() and __tep_data2host8().
The patch also alignes the libtraceevent summary man page with
these API changes.
