Original commit message from CVS: First round of changes to port to GObject. libgst.la compiles, though there are a few things commented out. Specifically object destruction is probably broken, but wtay gets to fix that because he researched the problem of glib 2.0 object destruction while doing the first round. Some of the XML stuff is commented out, but that's an easy fix. Next is the rest of the gst/ directory, then on to the plugins.
