Original commit message from CVS: summary: fix xml in gstreamer 1) make clear distinction between loading xml that actually creates objects and loading xml that just synchronizes properties with objects. moved most of gst_element_restore_thyself functionality to gst_xml_make_element. this new function name can change if it sucks. 2) many various fixes. createxml and runxml work now. 3) doc updates. 4) GstSignalObject is stil broken. i have no idea what it's supposed to do.
