WIP: This is mostly complete, but there is a problem: createDirectoryUnder
throws an error when annex.dbdir is set to outside the git repo.
annex.dbdir is a workaround for filesystems where sqlite does not work,
due to eg, the filesystem not properly supporting locking.
It's intended to be set before initializing the repository. Changing it
in an existing repository can be done, but would be the same as making a
new repository and moving all the annexed objects into it. While the
databases get recreated from the git-annex branch in that situation, any
information that is in the databases but not stored in the branch gets
lost. It may be that no information ever gets stored in the databases
that cannot be reconstructed from the branch, but I have not verified
that.

There is nothing in upgrade.log because it was never upgraded to version
9. Before, it would have never autoupgraded to 10, but it's entirely
safe to upgrade to 10 immediately.
Of course, annex.autoupgraderepository = false will prevent that
upgrade. So if someone for some reason really wants v9, they can set
that. I can't think of a reason someone would actually want v9 rather
than v10 though.

This would have prevented old git-annex from ever upgrading from v9 to
v10. Note that a manual `git-annex upgrade` can never run while the
assistant is running, so not <$> assistantrunning was always True,
so no matter what the timestamp of the v9 upgrade in the log, it would
decide there was old process danger.

That left the repo in v8, but with filter.annex.process set. Instead,
only warn, and defer the v10 upgrade.

The v10 upgrade should almost be safe now. What remains to be done is
notice when the v10 upgrade has occurred, while holding the shared lock,
and switch to using v10 lock files.

The upgrade from V9 uses this to avoid an automatic upgrade until 1 year
after the V9 update. It can also be used in future such situations.

v10 will run 1 year after the upgrade to v9, to give time for any v8
processes to die. Until that point, the v10 upgrade will be tried by
every process but deferred, so added support for deferring upgrades.
The upgrade prevention lock file that will be used by v10 is not yet
implemented, so it does not yet defer.
