rust-index: expose a method to retrieve the C index
The code for `shortesthexnodeidprefix` need to access the actual C index. For
now we grant its wish and expose a method to do so. Once we have the nodemap in
Rust, we will be able to implement the same feature from rust and we will be
able to drop this method.
