as nilskch points out in #1807, Rust 1.88.0 is stricter about
alignment.
because rust integers default to `i32`, we were casting a pointer
to an `i32` as a pointer to an `i64` causing a panic when dereferenced
due to misalignment as rust expects it to be 8 byte aligned.
I am currently working on upgrading Rust to the latest version
(https://github.com/tursodatabase/limbo/pull/1807). Initially, I wanted
to address all Clippy errors in that PR, but I decided to move them into
a separate one to make it easier to review.
**Note:** In the latest version of Clippy, it is considered an error to
place variables after a comma in string formatting macros (e.g.,
`format!`), rather than inside the `{}` placeholders. That's where most
of the errors are coming from.

Although concurrency doesn't work yet (#2059), we do want to support
concurrency, and one good first step is not to make the simulator hang
forever once any connection gets a `Busy` result from the VDBE

- Also added a benchmark for opening databases, the main thing that is
slowing `Database::open_file` is `parse_schema_rows`.
- `to_uppercase` was being called multiple times, leaving a relevant
mark on stack traces due to multiple allocations. `make_ascii_upper`
reuses the memory and is faster due to not handling unicode characters
(still compatible with sqlite).
- Do direct btree calls instead of creating a program for updating
`Schema` with `Schema::make_from_btree`.
- Faster type substr comparison using fixed size `u8` slices.

This inhibits ANSI color codes on non-TTY stdouts. It should fix logs
with mangled color codes such as

If I don't pipe or redirect, on this branch, the color is displayed.

the validation code was assuming that:
- if the parent has overflow cells after inserting a divider cell
- the exact divider we are validating MUST be in those overflow cells
However, this is not necessarily the case. Imagine:
- First divider gets inserted at index `n`. It is too large to fit, so
it gets pushed to `parent.overflow_cells()`. Parent usable space does
not decrease.
- Second divider gets inserted at index `n+1`. It is smaller, so it
still fits in usable space.
Hence:
Provide information to the validation function about whether the
inserted cell overflowed, and use that to find the left pointer and
assert accordingly.

We can use `right_page_id` directly to perform the validation instead of
carrying a raw pointer around which might be invalidated by the time we
do the validation.
