In order to prevent overconsumption of resources on the remote side QRTR implements a flow control mechanism. Move the handling of the incoming confirm_rx to the receiving process to ensure incoming flow is controlled. Then implement outgoing flow control, using the recommended algorithm of counting outstanding non-confirmed messages and blocking when hitting a limit. The last three patches refactors the node assignment and port lookup, in order to remove the worker in the receive path.
