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.
