Hook up pings and pongs received to go back to the right place. Look how simple that is!
This instead uses the events to open the path while the actor does other stuff. Opening the path involves the whole address/path validation dance so will take a while. This puts in the infrastructure to handle path events and figure out which events come from which connection.
need to check this out for real. wonder if this gets into loops
can't use task::yield_now in a sync function
There's a silly bug in how discovery is hooked up that if you don't do this check you fail hard. Rather than clean up that discovery logic I would prefer to just get on with the NodeStateActor refactor.
While that's currently possible, once we do QUIC-NAT-TRAVERSAL we can only do this once there's a connection anyway. So let's just delay this by another RTT.
- When a path is selected make sure it is open on all connections. - Do not open a path on a connection when it is already opened.
This no longer tries to figure out if discovery is needed based on how recently we may have communicated with a remote endpoint. Maybe that's too simple and we'll have to add back some extra check for discovery. But most active connections would have had a response by that time and not trigger the discovery.
The need for these was removed after the latest upstream quinn changes.
