sidedata: replace sidedata upgrade mechanism with the new one

Note: this is split into a separate change (like some other patches in this
series) because it's not easy to have all patches work 100% and this seemed
easier for reviewers.

When cloning or upgrading a repo, we may need to compute (or remove) sidedata.
This is the same mechanism that is used in exchange, so we re-use the new
system to simplify the code and fix the remaining issues (correctly dropping
flags and handling partial removal, etc.).

This also highlighted an issue with `test-copies-in-changeset.t` that kept
sidedata categories that are not relevant anymore. They should probably be
dropped entirely, but that would be for another patch.

"""strip changesets and their descendants from history (DEPRECATED)

The functionality of this extension has been included in core Mercurial
since version 5.7. Please use :hg:`debugstrip ...` instead.

This extension allows you to strip changesets and all their descendants from the
repository. See the command help for details.
