rust-lib: only export very common types to the top of the crate This was done very early in the Rust project's lifecycle and I had very little Rust experience. Let's keep the `DirstateParents` since they'll pop up in all higher-level code and make the rest more explicit imports to make the imports less confusing and the lib less cluttered.
