From: "Steven Rostedt (Google)" <rostedt@xxxxxxxxxxx>
Add a private field for tracecmd_input handle where callers can set it via
tracecmd_set_private() and retrieve it with tracecmd_get_private(). This
will allow a way to find specific information about a handle for users of
tracecmd_iterate_events_multi().
