* 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

* 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.
