* 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`

* Add comments to explain the need to flush sends ...
of take-over and event messages delivered over Sinks.
* Integrate use of identity keys into libp2p-noise.
In order to make libp2p-noise usable with a `Swarm`, which requires a
`Transport::Output` that is a pair of a peer ID and an implementation
of `StreamMuxer`, it is necessary to bridge the gap between static
DH public keys and public identity keys from which peer IDs are derived.
Because the DH static keys and the identity keys need not be
related, it is thus generally necessary that the public identity keys are
exchanged as part of the Noise handshake, which the Noise protocol
accomodates for through the use of handshake message payloads.
The implementation of the existing (IK, IX, XX) handshake patterns is thus
changed to send the public identity keys in the handshake payloads.
Additionally, to facilitate the use of any identity keypair with Noise
handshakes, the static DH public keys are signed using the identity
keypairs and the signatures sent alongside the public identity key
in handshake payloads, unless the static DH public key is "linked"
to the public identity key by other means, e.g. when an Ed25519 identity
keypair is (re)used as an X25519 keypair.

Thus the development transport needs to be still constructed with secio
for transport security when building for wasm.

* Give authentic DH keypairs a distinct type.
This has a couple of advantages:
* Signing the DH public key only needs to happen once, before
creating a `NoiseConfig` for an authenticated handshake.
* The identity keypair only needs to be borrowed and can be
dropped if it is not used further outside of the Noise
protocol, since it is no longer needed during Noise handshakes.
* It is explicit in the construction of a `NoiseConfig` for
a handshake pattern, whether it operates with a plain `Keypair`
or a keypair that is authentic w.r.t. a public identity key
and future handshake patterns may be built with either.
* The function signatures for constructing `NoiseConfig`s for
handshake patterns are simplified and a few unnecessary trait
bounds removed.
* Post-merge corrections.

The functionality is available through `Multiaddr::replace`.
What we currently call "nat_traversal" is merley a replacement of an IP
address prefix in a `Multiaddr`, hence it can be done directly on
`Multiaddr` values instead of having to go through a `Transport`.
In addition this PR consolidates changes made to `Multiaddr` in
previous commits which resulted in lots of deprecations. It adds some
more (see below for the complete list of API changes) and removes all
deprecated functionality, requiring a minor version bump.
Here are the changes to `multiaddr` compared to the currently published
version:
1. Removed `into_bytes` (use `to_vec` instead).
2. Renamed `to_bytes` to `to_vec`.
3. Removed `from_bytes` (use the `TryFrom` impl instead).
4. Added `with_capacity`.
5. Added `len`.
6. Removed `as_slice` (use `AsRef` impl instead).
7. Removed `encapsulate` (use `push` or `with` instead).
8. Removed `decapsulate` (use `pop` instead).
9. Renamed `append` to `push`.
10. Added `with`.
11. Added `replace`.
12. Removed `ToMultiaddr` trait (use `TryFrom` instead).
Replace the listener and address pair returned from `Transport::listen_on` with just a listener that produces `ListenerEvent` values which include upgrades as well as address changes.
