Previously `DELETE FROM ...` only emitted deletes for main table, but
this is incorrect as we want to remove entries from index tables as
well.
Closes#1383
I don't know when and why we dropped log::* in favor of tracing but when it was done, it made relevant logs not appear any more while debugging so... I added test_log::test which helps by automatically adding info logs from trace package.
We currently have two value types, `Value` and `OwnedValue`. The
original thinking was that `Value` is external type and `OwnedValue` is
internal type. However, this just results in unnecessary transformation
between the types as data crosses the Limbo library boundary.
Let's just follow SQLite here and consolidate on a single value type
(where `sqlite3_value` is just an alias for the internal `Mem` type).
The way this will eventually work is that we can have bunch of
pre-allocated `OwnedValue` objects in `ProgramState` and basically
return a reference to them all the way to the application itself, which
extracts the actual value.
Fix codegen for binary functions and add fuzz test for math functions
(we need to compile `rusqlite` with `-DSQLITE_ENABLE_MATH_FUNCTIONS` in
order to bundle sqlite with math functions compiled)

This is an attempt to move towards #881. I am not sure this is the
direction you want to take. In any case, I thought I would take a crack
at converting `values` from `Record` to private and see how bad it would
be.
In the end, as you can see, it is not so bad. I think performance-wise
it shouldn't be a bad hit with Rust's zero-cost abstraction. Also,
during the process I noticed a couple improvements that could be made
here and there but I honestly wanted to start with something small
enough that wouldn't be too hard to review.
Anyway, let me know if this is really how you would like to proceed.
Closes#962
