* [multistream-select] Fix panic with V1Lazy and add integration tests.
Fixes a panic when using the `V1Lazy` negotiation protocol,
a regression introduced in https://github.com/libp2p/rust-libp2p/pull/1484.
Thereby adds integration tests for a transport upgrade with both
`V1` and `V1Lazy` to the `multistream-select` crate to prevent
future regressions.
* Cleanup.
* Update changelog.
* Update atomic requirement from 0.4.6 to 0.5.0
Updates the requirements on [atomic](https://github.com/Amanieu/atomic-rs) to permit the latest version.

With b601ed4 libp2p-core requires the `Ord` bound on `Multiaddr`. This
bound is only implemented with parity-multiaddr `0.9.2`. Make sure
libp2p-core requires at least parity-multiaddr `0.9.2`.
* *: Prepare libp2p 0.28.1 release
* Simplify incoming connection handling.
Instead of handing out a mutable borrow to the connection
pool in the `IncomingConnectionEvent`, so one can call
`IncomingConnectionEvent::accept()`, just provide
`Network::accept()`.
* Update docs.
* Update CHANGELOG.
Previously a `Listener` would return its own address as the
`remote_addr` in the `ListenerEvent::Upgrade` event.
With this commit a `Listener` returns the dialer address as the
`remote_addr` in the `ListenerEvent::Upgrade` event. To do so a
`DialFuture` registers a port with the global `HUB` at construction
which is later on unregistered in the `Drop` implementation of the
dialer's `Chan`. The sending side of the `mpsc::channel` registered in
the `HUB` is dropped at `DialFuture` construction, thus one can not dial
the dialer port. This mimics the TCP transport behaviour preventing both
dialing and listening on the same TCP port.
* Remove temporary peer ID compatibility.
This removes the temporary compatibility mode between
peer IDs using identity hashing and sha256, thus being
the last step in the context of https://github.com/libp2p/rust-libp2p/issues/555.
* Check digest length in PeerId::from_multihash for Identity hash.
* Update core/src/peer_id.rs

* Allow override the yamux connection mode.
* Add `multiplex_ext` to transport `Builder`.
This method exposes the connection info and connected point to a provided
function which creates the upgrade and can base the decision on `PeerId`
or other connection information such as IP address.
* Re-export `yamux::Mode`.

With 826f513 a `StreamMuxer` can notify that the address of a remote
peer changed. This is needed to support the transport protocol QUIC as
remotes can change their IP addresses within the lifetime of a single
connection.
This commit implements the `NetworkBehaviour::inject_address_change`
handler to update the Kademlia routing table accordingly.
* Emit events for active connection close and fix `disconnect()`.
The `Network` does currently not emit events for actively
closed connections, e.g. via `EstablishedConnection::close`
or `ConnectedPeer::disconnect()`. As a result, when actively
closing connections, there will be `ConnectionEstablished`
events emitted without eventually a matching `ConnectionClosed`
event. This seems undesirable and has the consequence that
the `Swarm::ban_peer_id` feature in `libp2p-swarm` does not
result in appropriate calls to `NetworkBehaviour::inject_connection_closed`
and `NetworkBehaviour::inject_disconnected`. Furthermore,
the `disconnect()` functionality in `libp2p-core` is currently
broken as it leaves the `Pool` in an inconsistent state.
This commit does the following:
1. When connection background tasks are dropped
(i.e. removed from the `Manager`), they
always terminate immediately, without attempting
an orderly close of the connection.
2. An orderly close is sent to the background task
of a connection as a regular command. The
background task emits a `Closed` event
before terminating.
3. `Pool::disconnect()` removes all connection
tasks for the affected peer from the `Manager`,
i.e. without an orderly close, thereby also
fixing the discovered state inconsistency
due to not removing the corresponding entries
in the `Pool` itself after removing them from
the `Manager`.
4. A new test is added to `libp2p-swarm` that
exercises the ban/unban functionality and
places assertions on the number and order
of calls to the `NetworkBehaviour`. In that
context some new testing utilities have
been added to `libp2p-swarm`.
This addresses https://github.com/libp2p/rust-libp2p/issues/1584.

Signal the end of stream as `None` instead of producing a broken pipe error.
This restores the behaviour prior to PR #1196. I could not find a motivation
for this particular change in the PR and the previous implementation looks
correct to me.

* Add the libp2p-request-response protocol.
This crate provides a generic implementation for request/response
protocols, whereby each request is sent on a new substream.
* Fix OneShotHandler usage in floodsub.
* Custom ProtocolsHandler and multiple protocols.
1. Implement a custom ProtocolsHandler instead of using
the OneShotHandler for better control and error handling.
In particular, all request/response sending/receiving is
kept in the substreams upgrades and thus the background
task of a connection.
2. Support multiple protocols (usually protocol versions)
with a single `RequestResponse` instance, with
configurable inbound/outbound support.
* Small doc clarification.
* Remove unnecessary Sync bounds.
* Remove redundant Clone constraint.
* Update protocols/request-response/Cargo.toml
Co-authored-by: Toralf Wittner <tw@dtex.org>
* Update dev-dependencies.
* Update Cargo.tomls.
* Add changelog.
* Remove Sync bound from RequestResponseCodec::Protocol.
Apparently the compiler just needs some help with the scope
of borrows, which is unfortunate.
* Try async-trait.
* Allow checking whether a ResponseChannel is still open.
Also expand the commentary on `send_response` to indicate that
responses may be discard if they come in too late.
* Add `RequestResponse::is_pending`.
As an analogue of `ResponseChannel::is_open` for outbound requests.
* Revert now unnecessary changes to the OneShotHandler.
Since `libp2p-request-response` is no longer using it.
* Update CHANGELOG for libp2p-swarm.

* Add /dns protocol support to multiaddr
The /dns protocol has been added to the spec and has had a de-facto
meaning for years.
See https://github.com/multiformats/multiaddr/pull/100
This adds address parsing and encoding support for /dns to the multiaddr
format library.
* Cover Dns protocol in multiaddr property tests
* transports/dns: Support the /dns protocol
* Support /dns protocol in address translation
* Translate an FQDN URL into a /dns multiaddr
* transports/websocket: Support /dns multiaddr
* Use the /dns protocol in websocket redirects
The whole thing with back-translating from an redirect URL looks a bit
baroque, but at least now the transport does not completely ignore IPv6
addresses resolved from a hostname in a redirect URL.
* Add CHANGELOG entry

* Permit concurrent dialing attempts per peer.
This is a follow-up to https://github.com/libp2p/rust-libp2p/pull/1440
and relates to https://github.com/libp2p/rust-libp2p/issues/925.
This change permits multiple dialing attempts per peer.
Note though that `libp2p-swarm` does not yet make use of this ability,
retaining the current behaviour. The essence of the changes are that the
`Peer` API now provides `Peer::dial()`, i.e. regardless of the state in
which the peer is. A dialing attempt is always made up of one or more
addresses tried sequentially, as before, but now there can be multiple
dialing attempts per peer. A configurable per-peer limit for outgoing
connections and thus concurrent dialing attempts is also included.
* Introduce `DialError` in `libp2p-swarm`.
For a cleaner API and to treat the case of no addresses
for a peer as an error, such that a `NetworkBehaviourAction::DialPeer`
request is always matched up with either `inject_connection_established`
or `inject_dial_error`.
* Fix rustdoc link.
* Add `DialPeerCondition::Always`.
* Adapt to master.
* Update changelog.
