Summary: Re-implement the `findcommonheads` logic using `changelog` APIs that are going to have native support from Rust. This decouples from revlog-based Python DAG logic, namely `dagutil.revlogdag`, and `ancestor.incrementalmissingancestors`, unblocking Rust DAG progress, and cleans up the algorithm to not use revision numbers. The core algorithm is unchanged. The sampling logic is simplified and tweaked a bit (ex. no 'initial' / 'quick initial' special cases). The debug and progress messages are more verbose, and variable names are chosen to match the docstrings. I improved the doc a bit, and added some TODO notes about where I think can be improved.
