Original commit message from CVS: Merge the HEAD branch into AUTOPLUG2. More work on the negotiation process to allow for proxied negotiation which is needed in the queue. gst_pad_connect perform a negotiation and returns a gboolean indicating successfull connection. The pads are disconnected when negotiation fails. I'm not satisfied/sure about the implementation yet, needs some more investigation.
