`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
* [multistream-select] Listener conformity for failed negotiations.
When `V1Lazy` is used and the listener does not support the
optimistic (and singular) proposal of the dialer, it currently
happens that dialer and listener get a different outcome of
the negotiation. The dialer eventually detects the failed
negotiation as soon as it tries to read from the stream, but
the listener either encounters an invalid message or unexpected
premature EOF, depending on the payload that the dialer sent
prematurely after its protocol proposal. In these cases the
listener must be lenient and fail the negotiation "normally",
i.e. not with a protocol violation or an I/O error.

* Refine error handling.
Only be lenient with garbage or sudden EOF when reading
just after having sent a protocol rejection.

* 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
* 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.
* Update swarm/src/registry.rs

* 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*
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.
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.
* [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

* [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.
* Require remaining negotiation data to be flushed.
There appears to still be an edge-case whereby the
`remaining` data to send w.r.t. protocol negotiation to send
is successfully written before a `poll_read` on a `Negotiated` stream,
but where the subsequent `poll_flush()` is pending.
Now `remaining` is empty and the next `poll_read()`
will go straight to reading from the underlying
I/O stream, despite the flush not having happened
yet, which can lead to a form of deadlock during
protocol negotiation.
Rather than complicating the existing code further in
order to accommodate for this case, it seems preferable
to simplify the code by giving up on this optimisation
that only affects the last negotiation protocol message
sent by the "listener". So we give up on the ability
to combine data sent by the "listener" immediately
after protocol negotiation together with the final
negotiation frame in the same transport-level frame/packet.
* Update changelog.
* Add missing comma.
* core-derive: use full qualified name when polling NetworkBehaviour
If the users define a custom poll method also named in `poll` like
`#[behaviour(poll_method = "poll")`, it will cause issues as the wrong
`poll` method being called.
So use full qualified name to avoid ambiguity.
Fixes#1679.
* Update changelog for patch release.
