permit constants to be modified
...
We now track the last revision in which constants were modified. When
we see a constant query result, we record the current revision as
well. Then later we can check if the result is "still" constant. This
lets us cut out a lot of intermediate work.

convert DatabaseSlot to unsafe trait
...
The unsafe impl now asserts that the `DatabaseSlot` implementor type
is indeed `Send+Sync` if `DB::DatabaseData` is `Send+Sync`. Since our
query keys/values are a part of database-data, this means that `Slot`
must be `Send+Sync` if the key/value are `Send+Sync`. We test this
with a function that will cause compliation to fail if we accidentally
introduce an `Rc<T>` etc.
