rhg: fix bugs around [use-dirstate-tracked-hint] and repo auto-upgrade
This makes two changes:
- make rhg support the [dirstate-tracked-key-v1] requirement.
I believe rhg never changes the tracked file set, so it's OK that it
doesn't have any logic for writing this file.
- fix the name of [format.use-dirstate-v2.automatic-upgrade-of-mismatching-repositories]
config option in rhg, which makes rhg actually honor the auto-upgrade.
These two issues cancelled each other out in tests (auto-upgrade was happening
because [dirstate-tracked-key-v1] forced the fallback, not because of the config),
which is I think why they went unnoticed earlier.
