* Add listener ID and error event.
Report listener errors to client code so they are aware that an error
occurred within a listener. By default we continue to poll listeners
which produced an error, but clients can remove listeners by ID.
* tcp: Report errors.
Instead of silently waiting after errors we return all errors, but pause
after each error, before continuing.
* Add a test.
To ease testing, `Listener` is made generic and we test that no values
and errors are lost. Elapsed time between item generation is not
measured.
* Support the new methods in core-derive.
* Address review concerns.
* Remove `Display` impl of `ListenerId`.
* Add 'static bound to `on_listener_error` error.
* core/src/translation: Add unit tests
* core/src/translation: Support dns4 and dns6
Add dns4 and dns6 as valid protocol replacements for the origin address
to construct external addresses of a given node.
* core/nodes/network: %s/nat_translation/address_translation/
When receiving an observed address on a tcp connection that we initiated, the
observed address contains our tcp dial port, not our tcp listen port. We know
which port we are listening on, thereby we can replace the port within the
observed address.
When receiving an observed address on a tcp connection that we did **not**
initiated, the observed address should contain our listening port. In case it
differs from our listening port there might be a NAT along the path.
With the above in mind, the function name `nat_translation` is misleading.
* Rename RawSwarm* to Network*.
To complete the cut performed in [1].
The only remaining mention of a "swarm" in libp2p-core is in some tests
which actually depend on libp2p-swarm.

* Post-merge corrections.
* Replace unbounded channels with bounded ones.
To remove the unbounded channels used for communicating with node tasks
an API similar to `futures::Sink` is used, i.e. sending is split into a
start and complete phase. The start phase returns `StartSend` and first
attempts to complete any pending send operations. Completing the send
means polling until `Poll::Ready(())` is returned.
In addition this PR has split the `handled_node_tasks` module into
several smaller ones (cf. `nodes::tasks`) and renamed some types:
- `nodes::handled_node_tasks::NodeTask` -> `nodes::tasks::task::Task`
- `nodes::handled_node_tasks::NodeTaskInner` -> `nodes::tasks::task::State`
- `nodes::handled_node_tasks::NodeTasks` -> `nodes::tasks::Manager`
- `nodes::handled_node_tasks::TaskClosedEvent` -> `nodes::tasks::Error`
- `nodes::handled_node_tasks::HandledNodesEvent` -> `nodes::tasks::Event`
- `nodes::handled_node_tasks::Task` -> `nodes::tasks::TaskEntry`
- `nodes::handled_node_tasks::ExtToInMessage` -> `nodes::tasks::task::ToTaskMessage`
- `nodes::handled_node_tasks::InToExtMessage` -> `nodes::tasks::task::FromTaskMessage`
* `take_over_to_complete` can be an `Option`.
Since it is always holding just a single pending message.
* `send_event_to_complete` can be an `Option`.
