rust-cpython: rustdoc improvements
By default, `cargo doc` builds the documentation for public
constructs only, so we make public those that can. Since `cindex`
is not safe, we keep it private.
Unfortunately, the macro syntax of rust-cpython doesn't allow us
to document the classes directly, so we resort to do that at
the module level.
