 * macro for debugging output - cut down on #ifdef pollution.
 *
 * TRACE() is similar to ntpd's DPRINTF() for utilities and libntp.
 * Uses mprintf() and so supports %m, replaced by strerror(errno).
 *
 * The calling convention is not attractive:
 *     TRACE(debuglevel, (fmt, ...));
 *     TRACE(2, ("this will appear on stdout if debug >= %d\n", 2));
