impl Default, Copy, Clone for std::io::Sink and Empty
The omission of Sink: Default is causing me a slight inconvenience in a test harness. There seems little reason for this and Empty not to be Clone and Copy too. I have made all three of these insta-stable, because: AIUI Copycan only be derived, and I was not able to find any examples of how to unstably derive it. I think it is probably not possible. I hunted through the git history for precedent and found 79b8ad84c84481a43704213cd0948d2ba0ea63b4 Implement `Copy` for `IoSlice` https://github.com/rust-lang/rust/pull/69403 which was also insta-stable.
