Add buffer flags. The idea is to make it possible to easily check when a buffer contains control information that we need to parse to update the port fields. Make the client create remote nodes and ports and set up proxies for them. Make a port base class implementing most of the logic to pass buffers locally and remotely. Remove most code from stream.c, it's now in the port. Make a portsink and portsrc that can write and read to/from any port. We use these in the server to send and receive data. Rework format negotiation. The final format is now sent in-line before the data. The server will select a format on output ports.
