Mark `{Owned,Borrowed}{Fd,Socket}` as `rustc_nonnull_optimization_guaranteed`
so that they can be used in `Option` in FFI.
This allows the removal of the `allow(improper_ctypes)`.

rust-lang/rust#94586 is now in nightly, and the tests here now pass. I plan to submit the corresponding change to std too, but that needs to wait for rust-lang/rust#94586 landing in beta, which is used as the stage0 compiler. |
