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.
Use counters instead of void* to iterate items. This simplifies some
things and makes it easier to do over the wire.
Add format description to NodeInfo and use this to add format
descriptions to pinos devices.
Small fixes to fix leaks and crashes.
The proxy/resource ids are generated by the client and so we need to
used them as index in the client resource map instead of making our own
number.
Fix stream disconnect and client-node destroy
Fix gstreamer device provider
Make all sockets non-blocking to avoid errors with bad clients
Advertise the subsystems we monitor and disable the gstreamer monitors.
Implement core properties updates
Make sure we send REMOVE_ID after we are done with the resource.
