This reverts commit 9aed829.

Fixes #96435 , a regression
in crates doing use std::ffi::*; and use std::os::raw::*;.

We can re-add this re-export once the core::ffi types
are stable, and thus the std::os::raw types can become re-exports as
well, which will avoid the conflict. (Type aliases to the same type
still conflict, but re-exports of the same type don't.)

Hey! It looks like you've submitted a new PR for the library teams!

If this PR contains changes to any rust-lang/rust public library APIs then please comment with r? rust-lang/libs-api @rustbot label +T-libs-api -T-libs to request review from a libs-api team reviewer. If you're unsure where your change falls no worries, just leave it as is and the reviewer will take a look and make a decision to forward on if necessary.

Examples of T-libs-api changes:

  • Stabilizing library features
  • Introducing insta-stable changes such as new implementations of existing stable traits on existing stable types
  • Introducing new or changing existing unstable library APIs (excluding permanently unstable features / features without a tracking issue)
  • Changing public documentation in ways that create new stability guarantees
  • Changing observable runtime behavior of library APIs

As discussed in the libs-api meeting; could I get a review and beta-accepted on this?

Turns out we don't need to revert the whole core::ffi PR, just the re-export of those types in std::ffi. That makes this less urgent to re-add.

We can re-add this re-export once the `core::ffi` types
are stable, and thus the `std::os::raw` types can become re-exports as

still conflict, but re-exports of the same type don't.)
