tools lib traceevent: Implement new API tep_get_ref()



This patch implements a new API of the tracevent library:

  int tep_get_ref(struct tep_handle *tep);

The API returns the reference counter "ref_count" of the tep handler.
As "struct tep_handle" is internal only, its members cannot be accessed
by the library users, the API is used to get the reference counter.
