Original commit message from CVS: A first attempt to fix the queues in a cothreaded pipeline. Some fixes to the thread handling. Fix a bug in gstreamer-config : gthread was not included. gst_bin_create_plan() is now done in the READY state. a bin with only another bin in it will now work with gst_bin_iterate. Added some examples for the queues.
