rust-revlog: a trait for the revlog index

As explained in the doc comment, this is the minimum needed
for our immediate concern, which is to implement a nodemap
in Rust.

The trait will be later implemented in `hg-cpython` by the
index Python object implemented in C, thanks to exposition
of the corresponding functions as a capsule.

The `None` return cases in `node()` match what the `index_node()`
C function does.
