Summary:
A user hit cryptic error message:
File "revset.py", line 423, in ancestor
ancestors = repo.changelog.index.ancestors
AttributeError: 'list' object has no attribute 'ancestors'
That was because they have run `rm -rf` and the `.hg` directory was mostly
removed. `hg` falls back to revlog v0, and the code in question obviously
dislikes revlog v0.
Change the error message to just say repo corruption.
Since there are code depending on revlog v1, and we don't use v0 or v2. Remove
both of them.
