rust-pyo3: switch over to the pyo3 `InnerRevlog` This does many things that would involve a lot of churn if done separately: - Move the ancestors, revision and dagops modules to use the new `SharedByPyObject` instead of the old `UnsafePyLeaked` - Move the ancestors and discovery Python tests to using PyO3 - Change all calls to `importrust` to use `pyo3=True`, where applicable # Benchmarks I've run a bunch of benchmarks that involve revlog use. The TL;DR is that the pyo3 code is basically always very slightly faster if/when it's not within the noise levels.
