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.

impl<T> Query for T
where
    T: GetQueryTable<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.

b637e1a9bb mark runtime as UnwindSafe 
An alternative would be to mark bit of state as runtime safe, but as
Runtime directly contains a RefCell we need to mark it as a whole
anyway!

add15d83ea add panic hooks 
To implement cancellation via unwinding, one needs to throw `Canceled`
value in `if_current_revision_is_canceled` and `on_propagated_panic`.

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.

5a88871b9a improve snapshot docs 
Using two snapshots from the same thread isn't really very easy to do,
so we don't have to warn about that really (it's really nested use of
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.
