node: remove node state
...
Remove the node state. The state of the node is based on the state
of the ports, which can be derived directly from calling the port
methods. Track this state in the Port instead.
Add a mixer module that puts a mixer in from of audio sinks. This allows
multiple clients to play on one sink (still has some bugs). do some
fixes in the mixer and the scheduler to make this work.
