We haven't had any reports of problems from people who opted in. Since
it's early in the release cycle now, let's now test it on everyone who
builds from head, so we get almost a month of testing from those
people before it's enabled by default in a released version.
This impacts lots of test cases because the change-id header is added
to the Git commit. Most are uninteresting. `test_git_fetch` now sees
some divergent changes where it used to see only divergent bookmarks,
which makes sense.
With this change a warning is shown if the user does not explicitly specify the target revision, but the behavior is unchanged (it still defaults to the working copy).
In the future the warning will be turned into an error. In other words, it will be required to specify target revision.
The bulk of the changes here are to prepare tests for the upcoming change, to make the transition easier.

This adds a new `revsets.simplify-parents` configuration option (similar
to `revsets.fix`) which serves as the default revset for `jj
simplify-parents` if no `--source` or `--revisions` arguments are
provided.
The previous iteration of `jj simplify-parents` would only reparent the
commits in the target set in the `MutableRepo::transform_descendants`
callback. The subsequent `MutableRepo::rebase_descendants` call invoked
when the transaction is committed would then rebase all descendants of
the target set, which includes the commits in the target set again.
This commit updates the `MutableRepo::transform_descendants` callback to
perform rebasing of all descendants within the callback. All descendants
of the target set will only be rebased at most once.
