tests: clarify a comment describing a phabricator test scenario Per review feedback. Differential Revision: https://phab.mercurial-scm.org/D8455

phabricator: ensure that `phabsend` is given a contiguous, linear commit range Supplying a non-linear range was another orphan factory. While in theory there could be a use case for skipping over garbage commits (like adding debugging) and getting the valuable commits extracted out at the same time as posting a review, it seems far more likely that specifying a non-linear range is a user error. This is another case of issue6045, but predates both 0680b8a1992a and 601ce5392cb0. Neither the `--no-amend` case nor resubmitting a previously submitted commit would cause orphans. But for the sake of simplicity and to keep the parents tracked on Phabricator in the proper state, ban missing commits unconditionally. Differential Revision: https://phab.mercurial-scm.org/D8454

automation: support building Python 3 MSI installers This is very similar to what we just did for Inno. Differential Revision: https://phab.mercurial-scm.org/D8484

automation: support building Python 3 Inno installers The core packaging code now supports building Python 3 installers using PyOxidizer. Let's teach the automation code to invoke it so that we produce both Python 2 and Python 3 based exe installers. When publishing the artifacts, the Python 3 versions are preferred over the Python 2 versions given their higher weight (10 versus 9). This may be a controversial change. But I think making Python 3 the default is warranted, as it is the future. The Python 2 installers are still fully supported and can be installed should issues with Python 3 arise.
