Original commit message from CVS: This is a megapatch with the following changes: - moved the gchar *name to GstObject, removed the ones in GstElement and GstPad. - moved the parent handling completely into GstObject. This cause *all* of the plugins to fail (except those that used gst_pad_get_parent) - rearanged the XML save handling. - GstObject now has a class function save/restore_thyself. - GstObject has a generic method gst_object_save_thyself, this makes it possible to fire a signal wehever a new object is loaded. This is needed so we can add XML save hooks. - GstXML API has changed slightly. You now have to create a GstXML object first before you can actually load something. This makes it possible to attach a signal to GstXML whenever an object is loaded. I'm not sure we will keep this interface. - GstObject can now print the path_string without knowing about the GstPad and GstElement types. - Added gst_bin_get_by_name_recurse_up to lookup an element in the current element hierarchy. - added XML namespaces to the saved pipelines the namespace is: http://gstreamer.net/gst-core/1.0/ namespaces are needed to distinguish user generated XML from the core XML. Note that the plugins still contain a macro GST_OBJECT_PARENT that will be replaced with gst_pad_get_parent shortly.
