Reformat code with rustfmt

[anatol]

Keeping consistent code formatting across Rust projects is a great thing that simplifies learning new projects and getting familiar with its codebase. rustfmt is a standard tool that tries to achieve it. It would be really great if Rust developers use rustfmt for the core projects like libc.

@anatol Thanks for your suggestion! libc currently has a CI script for style validation (ci/style.rs), but perhaps you would like to improve upon it?

This has been done already, but I'm leaving this open because we are not currently blocking commits on being properly formatted with rustfmt yet.

This is blocked on: rust-lang/rustfmt#3253

Now rust-lang/rustfmt#3253 is closed and (when available) rustfmt is run on CI in ci/style.sh.

Is this issue solved ? Or should we ensure that rustfmt is always run (by using stable or a nightly with rustfmt) ?

Closing as resolved.
