* Make the lazy variant interoperable.
The remaining optimisation for `V1Lazy` for a listener
in the negotiation, whereby the listener delays flushing
of the multistream version header, is hereby removed.
The remaining effect of `V1Lazy` is only on the side of
the dialer, which delays flushing of its singular
protocol proposal in order to send it together with
the first application data (or an attempt is made to
read from the negotiated stream, which similarly
triggers a flush of the protocol proposal). This
permits `V1Lazy` dialers to be interoperable with
`V1` listeners. The remaining theoretical pitfall whereby
application data gets misinterpreted as another protocol
proposal by a listener remains, however unlikely.
`V1` remains the default, but we may eventually risk
just making this lazy dialer flush a part of the default
`V1` implementation, removing the dedicated `V1Lazy`
version identifier.
* Update CHANGELOG
* Separate versions from mere header lines.
Every multistream-select version maps to a specific header line,
but there may be different variants of the same multistream-select
version using the same header line, i.e. the same wire protocol.
* Cleanup
* Update misc/multistream-select/CHANGELOG.md
* Refactor and extend configurable connection limits.
To better track different connection counts, permit configurable
limits for these counts and make these available for
inspection efficiently, introduce dedicated connection counters
via a `ConnectionCounters` structure that is exposed on the
API via the `NetworkInfo`. All connection or connection
states that are counted in this way can also have effective
configurable limits.
* Cleanup
* Add missing file.
* Refine naming and config API.
* Update core/CHANGELOG.md

* Add "infinite" scores for external addresses.
Extend address scores with an infinite cardinal, permitting
addresses to be retained "forever" or until explicitly removed.
Expose (external) address scores on the API.

* Fix ls response encoding/decoding.
Thereby remove the now unnecessary arbitrary protocol name
length limit. Since it an 'ls' response is always terminated
with a dedicated newline (and thus ends with two newlines),
an 'ls' response with a single protocol can be disambiguated
from a single protocol response by this additional newline.
* More commentary
* Update versions and changelogs.
* Resolve remaining conflict.
* Permit empty ls responses, as before.
* feat: upgrade to multihash 0.13
`multihash` changes a lot internally, it is using stack allocation instead
of heap allocation. This leads to a few limitations in regards on how
`Multihash` can be used.
Therefore `PeerId` is now using a `Bytes` internally so that only minimal
changes are needed.
* Update versions and changelogs.

* multiaddr: feature gate url dependency
Make it possible to exclude url and its dependencies
from the dependency tree, by feature gating the
from_url* functions in the public API.
* Document feature gating of multiaddr::from_url*
* [mplex] Benchmark different split_send_size configurations.
With both TCP and memory transports. As a result, change the
default `split_send_size` to 8KiB.
* Cleanup
* [mplex] Update CHANGELOG.
* Add throughput information.
Without a limit, one can send malformed input such that seq.size_hint() returns
a very large value and crashes the program even if the following data is pretty
small.
* Retain remaining read buffer.
When the plaintext protocol handshake finishes and
the `Framed` I/O is discarded in favour of the underlying
I/O stream, the remaining read buffer of `Framed` must
be retained, as it may have buffered data beyond the
end of the handshake.
* Update versions and changelogs.
Treat EOF error as [`NegotiationError::Failed`], not as
[`NegotiationError::ProtocolError`], allowing dropping or closing an I/O stream
as a permissible way to "gracefully" fail a negotiation.
This is e.g. important when a listener rejects a protocol with
[`Message::NotAvailable`] and the dialer does not have alternative protocols to
propose. Then the dialer will stop the negotiation and drop the corresponding
stream. As a listener this EOF should be interpreted as a failed negotiation.
* Streamline mplex and yamux configurations.
* For all configuration options that exist for both multiplexers
and have the same semantics, use the same names for the
configuration.
* Rename `Config` to `YamuxConfig` for consistentcy with
the majority of other protocols, e.g. `MplexConfig`, `PingConfig`,
`KademliaConfig`, etc.
* Completely hide `yamux` APIs within `libp2p-yamux`. This allows
to fully control the libp2p API and streamline it with other
muxer APIs, consciously choosing e.g. which configuration options
to make configurable in libp2p and which to fix to certain values.
It does also not necessarily prescribe new incompatible version bumps of
yamux for `libp2p-yamux`, as no `yamux` types are exposed. The cost
is some more duplication of configuration options in the API, as well
as the need to update `libp2p-yamux` if `yamux` introduces new
configuration options that `libp2p-yamux` wants to expose as well.
* Update CHANGELOGs.
* Delay routing table update on new connections.
In order to avoid adding peers to the local routing table
which use a different protocol name and thus a different
overlay network, only update the local routing table
for newly established connections once the associated
connection handler reports that the protocol has been
confirmed.
* Update CHANGELOG.
* [multistream-select] Temp. disable "parallel" negotiation.
In order to later change the "ls" responses for spec-compliance.
* Update version.
* Update misc/multistream-select/CHANGELOG.md
