Updates work after cloning a damaged repo, if the damaged lfs objects aren't in
the update destination. Those objects won't be added to the new repo's store
because they aren't accessed.

Verify will copy/link all lfs objects into the local store that aren't already
present. Bypass the corrupted usercache to show that verify works when fed by
the (uncorrupted) remote store.

lfs -> normal -> lfs round trip conversions are possible. The threshold for the
lfs destination is specified here because it was originally listed in the local
.hgrc, and the global one is too high to trigger lfs usage. For lfs -> normal,
there's no 'lfs' destination repo requirement. For normal -> lfs, there is.
XXX: There's not a great way to ensure that the conversion to normal files
actually converts _everything_ to normal. The extension needs to be loaded for
the source, but there's no way to disable it for the destination. The best that
can be done is to raise the threshold so that lfs isn't used on the destination.
It doesn't like using '!' to unset the value on the command line.
