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.

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!

fe295c1b6e Add transparent query type
Transparent queries are not really queries: they are just plain
uncached functions without any backing storage.

Making a query transparent can be useful to figure out if caching it
at all is a win

d01d6ed511 Make GC API more orthogonal and flexible
Now, the effect of GC is a "product" of three parameters:

* what values are affected (everything/everything except used)
* are we removing values
* are we removing deps

SweepStrategy::default is now a no-op GC.
