This commit reverts the previous metrics behavior. Namely:
- adhering to --metrics-path flag
- listening on 0.0.0.0:8888 instead of 127.0.0.1:8080
Note that 8888 is the default IPFS debug (aka. metrics) port.
See https://github.com/mxinden/rust-libp2p-server/blob/master/src/metric_server.rs for previous behavior.
Pull-Request: #4392.
One needs to specify a version of `libp2p` dependeny in `misc/server/Cargo.toml` or import as a workspace dependency, in order to publish to crates.io.
This commit does the latter for the sake of consistency with the other libp2p-* dependencies.
Pull-Request: #4391.
Implements memory-based connection limits where the user can specify an absolute or a relative limit of the process' memory usage in relation to the available system memory.
Related: #4252.
Pull-Request: #4281.
The connection limit behaviour was not taking into account connection errors. Also, it was using the behaviour events to indicate established connections which is not always going to be the case because other behaviours can deny the connections (thanks @divagant-martian).

Pull-Request: #4250.
Since https://github.com/libp2p/rust-libp2p/pull/3973, gossipsub now fully supports wasm targets. It functions properly when added as a dependency on its own. However, when trying to use it under libp2p by activating a feature, it's not possible and the compiler will raise an error like `unresolved import libp2p::gossipsub`. This pull request enables the use of gossipsub for wasm targets when it's activated as a feature of the libp2p dependency.

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

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

All of the removed `dev-dependencies` are only for testing the upgrade procedure in `libp2p-core`. Ironically, this test does not use a single API of `multistream-select`. Thus, this test is simply misplaced in this crate. If we wanted to retain it, it should probably go into `libp2p` itself as that one already depends on all required crates.

With `Version::V1Lazy` and negotiation of a single protocol, a stream initiator optimistically
sends application data right after proposing its protocol. More specifically an application can
write data via `AsyncWrite::poll_write` even though the remote has not yet confirmed the stream protocol.
This saves one round-trip.
``` mermaid
sequenceDiagram
A->>B: "/multistream/1.0.0"
A->>B: "/perf/1.0.0"
A->>B: <some-perf-protocol-data>
B->>A: "/multistream/1.0.0"
B->>A: "/perf/1.0.0"
B->>A: <some-perf-protocol-data>
```
When considering stream closing, i.e. `AsyncWrite::poll_close`, and using stream closing as an
operation in ones protocol, e.g. using stream closing to signal the end of a request, this becomes tricky.
The behavior without this commit was as following:
``` mermaid
sequenceDiagram
A->>B: "/multistream/1.0.0"
A->>B: "/perf/1.0.0"
A->>B: <some-perf-protocol-data>
Note left of A: Call `AsyncWrite::poll_close` which first waits for the<br/>optimistic multistream-select negotiation to finish, before closing the stream,<br/> i.e. setting the FIN bit.
B->>A: "/multistream/1.0.0"
B->>A: "/perf/1.0.0"
Note right of B: Waiting for A to close the stream (i.e. set the `FIN` bit)<br/>before sending the response.
A->>B: FIN
B->>A: <some-perf-protocol-data>
```
The above takes 2 round trips:
1. Send the optimistic multistream-select protocol proposals as well as the initiator protocol
payload and waits for the confirmation of the protocols.
2. Close the stream, i.e. sends the `FIN` bit and waits for the responder protocol payload.
This commit proposes that the stream initiator should not wait for the multistream-select protocol
confirmation when closing the stream, but close the stream within the first round-trip.
``` mermaid
sequenceDiagram
A->>B: "/multistream/1.0.0"
A->>B: "/perf/1.0.0"
A->>B: <some-perf-protocol-data>
A->>B: FIN
B->>A: "/multistream/1.0.0"
B->>A: "/perf/1.0.0"
B->>A: <some-perf-protocol-data>
```
This takes 1 round-trip.
The downside of this commit is, that the stream initiator will no longer notice a negotiation error
when closing the stream. They will only notice it when reading from the stream. E.g. say that B does
not support "/perf/1.0.0", A will only notice on `AsyncRead::poll_read`, not on
`AsyncWrite::poll_close`. This is problematic for protocols where A only sends data, but never
receives data, i.e. never calls `AsyncRead::poll_read`. Though one can argue that such protocol is
flawed in the first place. With a response-less protocol, as even if negotiation succceeds, A
doesn't know whether B received the protocol payload.
Pull-Request: #4019.
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`.
Pull-Request: #3973.
