Allocates PeerId's on the stack, incidentally also making clippy happy. For more info see #1865. Superceeds #1865.

The direction looks good to me. Contrary to the PR description, I don't think this closes #1810, as we use bytes in a few other places throughout libp2p. It is also better not to address #1852 here, as that is unrelated. The build should be fixed separately either by upgrading rustls (#1852) or by async-tls-0.10.2 being yanked. See async-rs/async-tls#42.

Looks good to me. I'd just like to leave this PR open for a bit longer as the next libp2p release is just to update libp2p-mdns and libp2p-request-response, and this PR will essentially trigger new releases of most crates. It may also give more people the chance to comment here. If there are no objections we can probably merge and release this next week.

I am in favor of this patch. Thanks @dvc94ch.

Given that with this pull request PeerId implements Copy I would suggest removing all unnecessary clone() calls. What do you think?

I have run the benchmarks added in #1875 plus the additional sort_vec benchmark. See the result below.

$ git checkout master
$ cargo bench --bench peer_id -- --save-baseline master
$ git checkout peer-id-stack
$ cargo bench --bench peer_id -- --save-baseline peer-id-stack
$ critcmp master peer-id-stack

I plan to merge this later today. @mxinden Would a follow-up getting-started ticket for removing redundant .clone()s be acceptable? Since it is purely a syntactic simplification, I don't think we need to necessarily do that in this PR already.

* Prepare libp2p-websocket-0.26.1

* Update top-level libp2p-websocket patch version.

* [request-response] Refine success & error reporting for inbound requests. (libp2p#1867)

* Refine error reporting for inbound request handling.

At the moment one can neither get confirmation when a
response has been sent on the underlying transport, nor
is one aware of response omissions. The latter was
originally intended as a feature for support of
one-way protocols, which seems like a bad idea in
hindsight. The lack of notification for sent
responses may prohibit implementation of some
request-response protocols that need to ensure
a happens-before relation between sending a
response and a subsequent request, besides uses
for collecting statistics.

Even with these changes, there is no active notification
for failed inbound requests as a result of connections
unexpectedly closing, as is the case for outbound requests.
Instead, for pending inbound requests this scenario
can be identified if necessary by the absense of both
`InboundFailure` and `ResponseSent` events for a particular
previously received request. Interest in this situation is
not expected to be common and would otherwise require
explicitly tracking all inbound requests in the `RequestResponse`
behaviour, which would be a pity. `RequestResponse::send_response`
now also synchronously returns an error if the inbound upgrade
handling the request has been aborted, due to timeout or
closing of the connection, giving more options for graceful
error handling for inbound requests.

As an aside, the `Throttled` wrapper now no longer emits
inbound or outbound error events occurring in the context
of sending credit requests or responses. This is in addition
to not emitting `ResponseSent` events for ACK responses of
credit grants.

* Address some minor clippy warnings. (libp2p#1868)

In order to avoid emitting events relating to credit grants or acks
