Update to Mio v1

[Thomasdezeeuw]

Bumps the MSRV to 1.70.

One breaking changes is the removal of mio::net::SocketAddr, replacing it with std::os::unix::net::SocketAddr. The methods on the type should be the same.

For some smaller OS, such as ESP-IDF and Hermit, it can now be compiled without RUSTFLAGS.

Are you able to add a test for tokio-rs/mio#1749 (review) not being breaking in Tokio? I think we may not have a test for this case.

It seems like Tokio also has it's own version of SocketAddr, hence the only code change.

What are you looking for in a test for this?

E.g., calling UnixListener::bind with an abstract namespace.

Doesn't seem like UnixListener::bind supports abstract name spaces.

Just a status update on this. Before I merge this, the following steps need to happen:

1. Create an LTS release without the upgrade, which should hopefully last until debian stable adds support for rustc 1.70.
2. Increase MSRV to 1.70.

I've already prepared a PR for step 2, but I have not yet gotten around to step 1.

Are there any updates on this? Turns out mio v1 supports more platforms like QNX, making it possible to expand Tokio usage to new Rust targets. It sounds like this is purely a release packaging, rather than implementation issue. Thanks for working on this!

@nyurik the comment in #6635 (comment) is still up to date as far as I know, but due to summer vacations things are taking a little longer. I don't think there are any technical reasons this is blocked.

[Darksonn]

The update will happen some time next week.

[Darksonn]

@Thomasdezeeuw MSRV bump is merged. Please rebase this on master. Then I will make a release.

[atouchet]

Can #6154 be merged as well once Mio is updated?

[Thomasdezeeuw]

Seems some new tests were added that now fail, I'll take a look at

[Thomasdezeeuw]

CI should be fixed tokio-rs/mio#1817, so that means we need a Mio release first.

[Darksonn]

Once this is ready for review, mark the PR as non-draft.

[Thomasdezeeuw]

@Darksonn ready now, I was just waiting on the CI results.

Thank you.
