work on stream negotiation and start Add more buffer types to add and remove memory shared memory between the server and client. We would like to send buffers only once and then simply reference them by index. Do format negotiation and stream start with a START message.

Remove some events Remove port added and port removed, we can get that info by inspecting the port ids. Remove data from ringbuffer, we just need the ringbuffer to keep track of the read and write positions. Handle async-complete in the main thread Work on async node initialization Work on using a queue as the link between nodes Make the daemon link things based on the node states Use queue helper in v4l2

Remove port Remove the port object. We don't use it as a dbus object and we don't need it, we can use the link and node object directy. Move poll code and event handler to the node.
