Mentioning it here, though not directly related: I always confuse LIstenError, signaling a failure on upgrading an inbound connection, with the failure of listening on a new address. Anyone else?

A lot of naming could be improved here :)
I believe this is consistent with the naming of DialError but I agree that something like InboundConnectionError and OutboundConnectionError would probably be better.
I'll see to tidy up these when we remove the connection limits and banned variants.

Description
In case an error happens for an outgoing connection,
Poolreports anOutgoingConnectionError. This one is mapped to aDialErrorand reported viaSwarmEvent::OutgoingConnectionErrorandFromSwarm::DialFailure.For incoming connections, we didn't quite do the same thing. For one,
SwarmEvent::IncomingConnectionErrordirectly contained aPendingInboundConnectionError. Two,FromSwarm::ListenFailuredid not include an error at all.With this patch, we now introduce a
ListenErrorenum which we use inSwarmEvent::IncomingConnectionErrorand we pass a reference to it along inFromSwarm::ListenFailure.Notes
In #3254, I am going to introduce a
Deniedvariant in bothDialErrorandListenErrorwhich contains the error that aNetworkBehaviourdenied a connection with.Links to any relevant issues
