Please see the individual commits.

I am particularly curious why vec! was compiling in 1.56.0 (@bjorn3?).

v2:

@wedsonaf Please take a look at the sysctl change.

Fixes #585.

In particular, I am particularly curious why vec! was compiling in 1.56.0 (@bjorn3?).

Probably caused by rust-lang/rust#89030 and rust-lang/rust#89036. I suspect previously it would have failed to compile if the function was actually codegened, just not when defined. Is Sysctl::register used anywhere?

That seems to be the case indeed -- I just force-called it from 1.56.0 and got the error. Thanks!

`vec!` may allocate, which in turn requires the `exchange_malloc`
`lang_item`. For some reason, in 1.56.0 this compiled.

This triggered a new Clippy lint in 1.57.0.
