ccb85989bc rename durability_last_changed_revision to last_changed_revision

86dfdd1fda permits things to become *more* durable without a "change"
This will be important if we want to automatically upgrade the
durability of inputs.

0a5b6b0451 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.

e7d704dd8b 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.

e9f91f03a5 roll our own lru list
We could use e.g. intrusive-collections but from reading the docs and
surveying the source it wasn't *obvious* to me that it had the right
semantics.
