Implement the libp2p rendezvous protocol.
> A lightweight mechanism for generalized peer discovery. It can be used for
bootstrap purposes, real time peer discovery, application specific routing, and
so on.

Require `NetworkBehaviourAction::{DialPeer,DialAddress}` to contain a
`ProtocolsHandler`. This allows a behaviour to attach custom state to its
handler. The behaviour would no longer need to track this state separately
during connection establishment, thus reducing state required in a behaviour.
E.g. in the case of `libp2p-kad` the behaviour can include a `GetRecord` request
in its handler, or e.g. in the case of `libp2p-request-response` the behaviour
can include the first request in the handler.
Return `ProtocolsHandler` on connection error and close. This allows a behaviour
to extract its custom state previously included in the handler on connection
failure and connection closing. E.g. in the case of `libp2p-kad` the behaviour
could extract the attached `GetRecord` from the handler of the failed connection
and then start another connection attempt with a new handler with the same
`GetRecord` or bubble up an error to the user.

- Change `PublicKey::into_protobuf_encoding` to
`PublicKey::to_protobuf_encoding`.
- Change `PublicKey::into_peer_id` to `PublicKey::to_peer_id`.
- Change `PeerId::from_public_key(PublicKey)` to
`PeerId::from_public_key(&PublicKey)`.
- Add `From<&PublicKey> for PeerId`.

* Fix needless question mark operator
* Don't convert from u64 to u64
LocalStreamId is already a u64, no need to convert.
* Don't use `.into()` to convert to the same type
* Don't specify lifetime if it can be inferred
* Use `vec!` macro if we immediately push to it
This creates the vector with the appropriate capacity.
* Don't index array when taking a reference is enough

1. Deprecating the `write_one` function
Semantically, this function is a composition of `write_with_len_prefix` and
`io.close()`. This represents a footgun because the `close` functionality is
not obvious and only mentioned in the docs. Using this function multiple times
on a single substream will produces hard to debug behaviour.
2. Deprecating `read_one` and `write_with_len_prefix` functions
3. Introducing `write_length_prefixed` and `read_length_prefixed`
- These functions are symmetric and do exactly what you would expect, just
writing to the socket without closing
- They also have a symmetric interface (no more custom errors, just `io::Error`)

libp2p-dns requires a new feature in parity-multiaddr v0.11.2 namely
Multiaddr::ends_with. libp2p-dns does not depend on parity-multiaddr
directly but through libp2p-core. Prepare a new version of libp2p-core
requiring at least parity-multiaddr v0.11.2 and update libp2p-dns to
require libp2p-core v0.28.1.
* Implement `/dnsaddr` support on `libp2p-dns`.
To that end, since resolving `/dnsaddr` addresses needs
"fully qualified" multiaddresses when dialing, i.e. those
that end with the `/p2p/...` protocol, we make sure that
dialing always uses such fully qualified addresses by
appending the `/p2p` protocol as necessary. As a side-effect,
this adds support for dialing peers via "fully qualified"
addresses, as an alternative to using a `PeerId` together
with a `Multiaddr` with or without the `/p2p` protocol.
* Adapt libp2p-relay.
* Update versions, changelogs and small cleanups.
* Shorten and unify Debug impls of public keys.
ed25519 `PublicKey` and secp256k1 `PublicKey` get a new `Debug`
impl, while RSAs `PublicKey` is aligned with the others for uniformity.
* Update version and changelog.
* Make clippy "happy".
Address all clippy complaints that are not purely stylistic (or even
have corner cases with false positives). Ignore all "style" and "pedantic" lints.
* Fix tests.
* Undo unnecessary API change.
Move transport upgrade protocols from `protocols/`
to `transports/`, such that only "application protocols"
that depend on `libp2p-swarm` remain in `protocols/`,
whereas there is no such dependency in `transports/`
outside of integration tests.
Tweak README and top-level CHANGELOG.
* 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

* Restore chat-tokio example.
* Forward poll_write_vectored for tokio's AsyncWrite.
* Update changelogs.

`futures-codec` has not been updated in the recent months. It still
depends on `bytes` `v0.5` preventing all downstream dependencies to
upgrade to `bytes` `v1.0`.
This commit replaces `futures_codec` in favor of `asynchronous-codec`
The latter is a fully upgraded fork of the former.
In addition this commit upgrades:
- bytes to v1
- unsigned-varint to v0.6.0
- prost to v0.7
* core: Add rudimentary benchmark for PeerId::from_bytes and clone
* .github/workflow: Include benchmarks
To ensure changes through pull requests won't make benchmarks fail to
compile or run, run them as part of CI.
