Wim Taymans 021eccb8ad Fix stream restart 
Make sure we always send a clock update before sending a start command.
Fix memory size.
Follow the state of the node to do allocation
Use the pinos node to control the state
When doing STREAMOFF, all buffers will be dequeued. requeue them buffers
for when we go to playing again.
