In gstreamer commit f712a9596c2bc1863edf9b816d9854eefca9ba45 gst_message_new_duration was renamed to gst_message_new_duration_changed.
However the only place where we used this is in the HTTP source element and only if appsrc < 0.10.27 is used at runtime. In the case of GStreamer 1.0 this condition will be always false so we can disable this code at build time.
