copies-rust: rename Oracle.is_ancestor to Oracle.is_overwrite
The core information that we want here is about "does information from revision
X overwrite information in Y". To do so, we check is X is an ancestors of Y, but
this is an implementation details, they could be other ways. We update the
naming to clarify this (and align more with wording used in upcoming changesets.
For people curious about other ways: for example we could record the overwrite
graph as it happens and reuse that to check if X overwrite Y, without having to
do potential expensive `is_ancestor` call on the revision graph.

== New Features == * The amend extension supports the `--currentuser` argument. * The amend extension supports the `--close-branch` argument. * The amend extension supports the `--secret` argument. * The uncommit extension supports the `rewrite.update-timestamp` config option. == New Experimental Features == == Bug Fixes == == Backwards Compatibility Changes == * A shell that supports `$(command)`` syntax for command substitution is now required for running the test suite. The test runner normally uses `sh`, so if that is a shell that doesn't support `$(command)` syntax, you can override it by setting `$HGTEST_SHELL` or by passing it to `run-tests.py --shell <shell>`. * The (experimental) narrow extension's wire protocol changed. If you're using it, you'll need to make sure to upgrade server and client at the same time. == Internal API Changes ==
