rust: add `UncheckedRevision` type
This is the start of a series whose aim is to separate "checked" and
"unchecked" revision numbers. A "checked" revision number is valid for a given
index, allowing us to have faster algorithms that don't do redundant checks
all the time and have a clearer view of the kinds of revisions
we're working with.
