0a94efeac3 emit WillChangeInputValue before new revision (breaking change!) 
Otherwise we need to borrow the `db` in `with_incremented_revision`
and it's a pain.

8c133e7a4d make synthetic_write require &mut self (breaking change!) 
This was an oversight before -- the current type implies that
one introduce a synthetic write (and hence a new revision) from
a `Frozen<DB>`! Not cool.

0e01067d55 feat: Allow queries to avoid panics on cycles 
Quickest POC I could create to get some potentially cyclic queries to
not panic and instead return a result I could act on. (gluon's module
importing need to error on cycles).

```
// Causes `db.query()` to actually return `Result<V, CycleError>`
fn query(&self, key: K, key2: K2) -> V;
```

A proper implementation of this would likely return
`Result<V, CycleError<(K, K2)>>` or maybe larger changes are needed.

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.

fcc7058e9c implement strong panic safety 
Previosly, panicking query would remove in-progress memos from the
table.

However, we use panic for cancellation, so it's reasonable to **not**
remove the old result after panic. This is also known as string
exception safety guarantee: not only database is in *some* consistent
state after a panic, it is in the same state it was before the panic!

0f577a2b10 generate an impl of the trait from procedural macro 
Instead of generating

```rust
trait Query: GetQueryTable<Foo> {
    fn foo() { .. }
}
```

generate

```rust
trait Query {
}

impl<T> Query for T
where
    T: GetQueryTable<Foo>,
{
    fn foo() { .. }
}
```

93c30a953d make query_group macro procedural 
Switch to a procedural implementation of the `query_group!` macro,
residing in the `components/salsa_macros` subcrate.

Allow the user to override the invoked function via `salsa::invoke(...)`
and the name of the generated query type via `salsa::query_type(...)`.

In all tests, replace the `salsa::query_group! { ... }` invocations with
the new attribute-style `#[salsa::query_group]` macro, and change them
to the new naming scheme for query types (`...Query`).

Update README, examples, and documentation.

Runtime directly contains a RefCell we need to mark it as a whole
anyway!

Aleksey Kladov
a2198f1f8a prevent untracked queries from moving brackwards in time 
If a query observes an untracked read, it gets changed_at equal to the
current revision. When we re-validate the query later, if it doesn't
do an untracked read this time, it gets changed_at equal to the
maximum of the dependencies. Crucially, this new changed_at may
be **older** then the previous value of changed_at. That is, we break
the rule that `changed_at` monotonically increases.

This can lead to missed re-executions down the line (see the added
test).

3cde493e4e remove the virtual fn call for creating query descriptors 
Previously, to "make the connection" between the database type `DB` and
the query type `Q`, we were passing down a fn pointer that would crate
the query descriptor. But now we have this `GetQueryTable` trait -- use
that instead.

Using two snapshots from the same thread isn't really very easy to do,

snapshots that's a problem, and to do that you have to use thread-locals
or something just to get the snapshot *into* the database -- at that
point, something is really going wrong)).

d429926ddd treat constants more uniformly 
We used to ignore constant inputs entirely. We now track them, but if we
find that a value is constant, we discard ITS inputs.  This means that
-- if we track dependencies -- we have an "outer rim" of constant
values.

Also take the opportunity to reshuffle how derived inputs represent
their state.
