subrepo: introduce the nullsubrepo() method
This will be used in an upcoming patch. It's a one-off use, but seems better to
be contained in the subrepo module, than for the next patch to overwrite the
_ctx and _state fields in another module. '' is used as the default revision in
subrepo.state() if it can't be found, so it seems like a safe choice.
