As part of [RFC 474](https://github.com/rust-lang/rfcs/pull/474), this commit renames `std::path` to `std::old_path`, leaving the existing path API in place to ease migration to the new one. Updating should be as simple as adjusting imports, and the prelude still maps to the old path APIs for now. [breaking-change]
