revlog: add a Rust implementation of `headrevsdiff` Python implementation of `headrevsdiff` can be very slow in the worst case compared with the `heads` computation it replaces, since the latter is done in Rust. Even the average case of this Python implementation is still noticeable in the profiles. This patch makes the computation much much faster by doing it in Rust.
