Applied to `rust-next` -- thanks everyone!

    [ Used the `cfg_attr` from the TODO comment and clarified its comment
      now that the stabilization is in beta and thus quite likely stable
      in Rust 1.88.0. Simplified the `new_body` code by introducing a new
      variable. Added `#[allow(clippy::incompatible_msrv)]`. - Miguel ]

    [ Used `::kernel` for paths. - Miguel ]

    [ Split from the next commit as suggested by Tamir. - Miguel ]

    [ Split the `CString` simplification into a new commit. - Miguel ]

Cheers,
Miguel
