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.

More work on implementing remote protocol Rework things so that we negotiate buffer pools beforehand and only pass buffer ids around We can then remove the refcount of buffers, events and commands. More work on buffer reuse Use the node state changes to trigger the next step in the configuration sequence. Move most of the client-node to a plugin Do buffer allocation in the port link.

Keep track of where the buffers was allocated. Make some more convenience functions to initialize buffer headers.

Add support for async results Add an async result code and an event to signal the completion. Use async return values to signal completion of a method and potential state change. Add selected format to port update message. Make it possible to parse into a custom copy of the command memory. Remove state change events from the elements, we now just update the state. Implement async results in the proxy element Add support for removing buffers in the client. Fix up pinossink Deal with async return in the links.

Add support for async results Add an async result code and an event to signal the completion. Use async return values to signal completion of a method and potential state change. Add selected format to port update message. Make it possible to parse into a custom copy of the command memory. Remove state change events from the elements, we now just update the state. Implement async results in the proxy element Add support for removing buffers in the client. Fix up pinossink Deal with async return in the links.
