Needs a rebase.

Is there any way we can use io-lifetimes or a similar crate to avoid an MSRV bump?

@asomers rebased.

@notgull The rationale was that moving to I/O safety is already a massive breaking change, so a MSRV bump shouldn't add extra pain.

Some clippy lints I applied were false positives that needed the 2021 edition, so I bumped us up to that.

#1861 should be merged first because clippy changed stuff in the code we're deleting.

It looks like the OSX build failed because it tried to download cargo-hack exactly as that project uploaded a new release.

I copied this from the other setup_script blocks. If you remove this I'm pretty sure the build fails with a wrong rust version error.

And yet the old version didn't fail. I think this section is masking some other problem.

Make this change and I don't think you'll need to reinstall the toolchain on line 159 below.

There's more formatting changes like this mixed in with content changes. Can you please move them into separate commits?

I thought this was due to the edition bump, but it looks like this is because I'm on nightly? When I run a cargo fmt on master this stuff changes. Created #1909
