The SQLite varint specification states that the varint is guaranteed to be a maximum of 9 bytes, but our version of write_varint initializes a buffer of 10 bytes. Changing the size to match the specification.
The `run_once()` name is just a historical accident. Furthermore, it now
started to appear elsewhere as well, so let's just call it IO::step() as we
should have from the beginning.
This PR updates to version Rust 1.88.0 ([Release
notes](https://releases.rs/docs/1.88.0/)) and fixes all the clippy
errors that come with the new Rust version.
This is possible in the latest Rust version:
```rust
if let Some(foo) = bar && foo.is_cool() {
...
}
```
There are three complications in the migration (so far):
- A BUNCH of Clippy warnings (mostly fixed in
https://github.com/tursodatabase/limbo/pull/1827)
- Windows cross compilation failed; linking `advapi32` on windows fixes
it
- Since Rust 1.87.0, advapi32 is not linked by default anymore

- Rust is more strict with FFIs and aligning pointers now. CI checks
failed with error below
- Fixed in https://github.com/tursodatabase/turso/pull/2064
