2024-04-17session: force session cleanups on app detachFlorin Coras1-6/+23
Force transport and session cleanup on session detach if transport is already closing. This should also avoid races between transport initiated session cleanups and pending session control events.

2024-01-09session: support for cl port reuseFlorin Coras6-24/+147
Adds support for connectionless listener port reuse. Until now, cl listeners had fifos allocated to them and therefore only one app worker could ever listen, i.e., a session cannot have multiple fifos. To circumvent the limitation, this separates the fifos from the listener by allocating new cl sessions for each app worker that reuses the app listener. Flows are hashed to app worker cl sessions but, for now, this is not a consistent/fixed hash.

2023-08-09session: async rx event notificationsFlorin Coras11-580/+835
Move from synchronous flushing of io and ctrl events from transports to applications to an async model via a new session_input input node that runs in interrupt mode. Events are coalesced per application worker. On the one hand, this helps by minimizing message queue locking churn. And on the other, it opens the possibility for further optimizations of event message generation, obviates need for rx rescheduling rpcs and is a first step towards a fully async data/io rx path.
