Change `Stream` implementation of `ExpandedSwarm` to return all
`SwarmEvents` instead of only the `NetworkBehaviour`'s events.
Remove `ExpandedSwarm::next_event`. Users can use `<ExpandedSwarm as
StreamExt>::next` instead.
Remove `ExpandedSwarm::next`. Users can use `<ExpandedSwarm as
StreamExt>::filter_map` instead.
Remove `Deref` and `DerefMut` implementations previously dereferencing
to the `NetworkBehaviour` on `Swarm`. Instead one can access the
`NetworkBehaviour` via `Swarm::behaviour` and `Swarm::behaviour_mut`.
Methods on `Swarm` can now be accessed directly, e.g. via
`my_swarm.local_peer_id()`.
Reasoning: Accessing the `NetworkBehaviour` of a `Swarm` through `Deref`
and `DerefMut` instead of a method call is an unnecessary complication,
especially for newcomers. In addition, `Swarm` is not a smart-pointer
and should thus not make use of `Deref` and `DerefMut`, see documentation
from the standard library below.
> Deref should only be implemented for smart pointers to avoid
confusion.

* Update tomls.
* Let transports decide when to translate.
* Improve tcp transport.
* Update stuff.
* Remove background task. Enhance documentation.
To avoid spawning a background task and thread within
`TcpConfig::new()`, with communication via unbounded channels,
a `TcpConfig` now keeps track of the listening addresses
for port reuse in an `Arc<RwLock>`. Furthermore, an `IfWatcher`
is only used by a `TcpListenStream` if it listens on any interface
and directly polls the `IfWatcher` both for initialisation and
new events.
Includes some documentation and test enhancements.
* Reintroduce feature flags for tokio vs async-io.
To avoid having an extra reactor thread running for tokio
users and to make sure all TCP I/O uses the mio-based
tokio reactor.
Thereby run tests with both backends.
* Add missing files.
* Fix docsrs attributes.
* Update transports/tcp/src/lib.rs
