rust-nodemap: abstracting the indexing

In the forthcoming mutable implementation, we'll have to visit
node trees that are more complex than a single slice, although
the algorithm will still be expressed in simple indexing terms.

We still refrain using `#[inline]` indications as being
premature optimizations, but we strongly hope the compiler will
indeed inline most of the glue.
