A first attempt to fix the queues in a cothreaded pipeline.

Browse source 
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.
