revlog: signal which revlog index are compatible with Rust
Otherwise, Rust may treat python object like `cindex` object, leading to
trouble. The new attribute is an integer because I expect we might need a flag
field in the future.
As a start we get the rust code to raise a clear TypeError. We will use the
information in a smarter way in the next changesets.
