This resolves an issue where our tests were depending on the number of network interfaces available on the local machine.

Instead of exposing the time to establish a connection, the time to upload the bytes and the time to download the bytes, expose a single time including all three.
The rational here is, that differentiation of the three is flawed. E.g. when does one stop the upload timer and start the download timer? When the last byte is sent? When the last byte is flushed? When the first byte is received?
See https://github.com/libp2p/test-plans/pull/184#pullrequestreview-1482600521 for past discussion.

Using workspace inheritance breaks `cargo release` because it cannot resolve that the dev-dependencies should only use a `path` and not a version.

Remove the use of the core `upgrade::transfer` module in `ping` example (`request-response` protocol) in favor of `cbor` codec.

Currently, the kademlia behaviour can only learn that the remote node supports kademlia on a particular connection if we successfully negotiate a stream to them.
Using the newly introduced abstractions from #3651, we don't have to attempt to establish a stream to the remote to learn whether they support kademlia on a connection but we can directly learn it from the `ConnectionEvent::RemoteProtocolsChange` event. This happens directly once a connection is established which should overall benefit the DHT.
Clients do not advertise the kademlia protocol and thus we will immediately learn that a given connection is not suitable for kadmelia requests. We may receive inbound messages from it but this does not affect the routing table.

Rewrite `libp2p-perf` protocol using `libp2p-request-response`. Additionally adjust to latest conventions, e.g. the final JSON output.

This modification removes deprecated dependency `wasm_timer` and enables wasm compatibility on the gossibsup protocol by simply substituting the `wasm_timer::Instant` with `instant::Instant`(which supports `fn checked_add`) and `wasm_timer::Interval` with `futures_ticker::Ticker`.

Peer discovery with mDNS can be very slow, particularly if the first mDNS query is lost. This patch resolves it by adjusting the timer with an adaptive initial interval. We start with a very short timer (500 ms). If a peer is discovered before the end of the timer, then the timer is reset to the normal query interval value (300s), otherwise the timer's value is multiplied by 2 until it reaches the normal query interval value.

Now that we have the infrastructure for notifying protocols about changes to our listen protocols, we can use this to actively push those changes to our remotes. This allows other peers to re-configure themselves with very low-latency instead of waiting for the periodic identify event.
Resolves: #3613.
Pull-Request: #3980.
Previously, the `libp2p-ping` module came with a policy to close a connection after X failed pings. This is only one of many possible policies on how users would want to do connection management.
We remove this policy without a replacement. If users wish to restore this functionality, they can easily implement such policy themselves: The default value of `max_failures` was 1. To restore the previous functionality users can simply close the connection upon the first received ping error.
In this same patch, we also simplify the API of `ping::Event` by removing the layer of `ping::Success` and instead reporting the RTT to the peer directly.

This patch adds two modules to `libp2p::request_response`:
- `cbor`
- `json`
Both define a `Behaviour` type-alias that comes with a `Codec` implementation which uses the respective `serde` crate to serialize and deserialize the messages.
Fixes#3905.
Pull-Request: #3952.
Previously, a `NetworkBehaviour` could report an `AddressScore` for an external address. This score was a `u32` and addresses would be ranked amongst those.
In reality, an address is either confirmed to be publicly reachable (via a protocol such as AutoNAT) or merely represents a candidate that might be an external address. In a way, addresses are guilty (private) until proven innocent (publicly reachable).
When a `NetworkBehaviour` reports an address candidate, we perform address translation on it to potentially correct for ephemeral ports of TCP. These candidates are then injected back into the `NetworkBehaviour`. Protocols such as AutoNAT can use these addresses as a source for probing their NAT status. Once confirmed, they can emit a `ToSwarm::ExternalAddrConfirmed` event which again will be passed to all `NetworkBehaviour`s.
This simplified approach will allow us implement Kademlia's client-mode (https://github.com/libp2p/rust-libp2p/issues/2032) without additional configuration options: As soon as an address is reported as publicly reachable, we can activate server-mode for that connection.
