Apparently these aren't guaranteed to be the same, and are merely "always the same in practice" (see https://rust-lang.zulipchat.com/#narrow/stream/136281-t-lang.2Fwg-unsafe-code-guidelines/topic/.60usize.60.20vs.20.60size_t.60).

This is a big footgun, but I suspect it can be alleviated if we expose this and start migrating people to it in advance of any platforms that ever have this as different.

I'll file a tracking issue after this gets some traction.

Looks good to me. r=me once you file the tracking issue and change the PR to use that issue number.

I have no problem with the PR itself, I just don't think the API is necessary. If you disagree, merge it — it's not like it's insta-stable or anything.

Actually, never mind. I didn't realize until just now that the std::os::raw module existed. This PR fills an API hole that currently exists, so it's a 👍 from me.

Add `c_size_t` and `c_ssize_t` to `std::os::raw`.
