although 32 is prefect fine in our case, it would be consistent to use the const value PING_SIZE.

* 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

* [libp2p-kad] Provide more insight and control into Kademlia queries.
More insight: The API allows iterating over the active queries and
inspecting their state and execution statistics.
More control: The API allows aborting queries prematurely
at any time.
To that end, API operations that initiate new queries return the query ID
and multi-phase queries such as `put_record` retain the query ID across all
phases, each phase being executed by a new (internal) query.

`FixedPeersIter` requires the initial set of peers to be passed as
`PeerId`s and not as `Key<PeerId>`s. This commit removes the unnecessary
conversion.
Instead of creating unconstrained random number generators in quickcheck
tests to generate test data, have quickcheck provide a `Seed` to seed
those random number generators and thus make the test execution
deterministic / reproducible.
* 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.
Make sure to decrease `num_waiting` when being notified of a peer
failure to allow an additional peer to be queried.
Given that `FixedPeersIter` is initialized with `replication_factor` by
`QueryPool` this bug will not surface today.
If a user sends a message that is over the maximum transmission size gossipsub
will disconnect from the peer being sent the message.
This PR updates the logic to simply emit an error, not send the over-sized
message but maintain the long-lived streams for future messages.

Macro was using field_n (field index including ignored fields) for calculations instad of
enum_n (field index excluding ignored fields). When calculating te nesting the calculation
was made between the number of non-ignored fields and a field_n that lead to and overflow.

* tcp: Set IPV6_V6ONLY for IPv6 listeners.
The current behaviour of listening on an IPv6 address varies depending
on the operating system's IP address stack implementation. Some support
IPv4-mapped IPv6 addresses (e.g. Linux and newer versions of Windows)
so a single IPv6 address would support IPv4-mapped addresses too.
Others do not (e.g. OpenBSD). If they do, then some support them by
default (e.g. Linux) and some do not (e.g. Windows).
This PR attempts to implement the same behaviour accross operating
systems. The strategy is as follows:
Disable IPv4-mapped IPv6 addresses, hence the socket option IPV6_V6ONLY
is always set to true.
This allows binding two sockets to the same port and also avoids the
problem of comparing mixed addresses which leads issues such as #1552.
* Update CHANGELOG and address review concerns.
* Update CHANGELOG.md
