Resolves#2677
- Implements the modifier for Floor on the datetime object.
- Implements the modifier for Ceiling on the datetime object.
- Includes additional testing changes in testing/scalar-functions-
datetime.test to test the sql functionality.
Consolidation PR of #2678 and #2679 since the functions ended up being
much more complicated than I initially thought and had to be done in a
single PR.
Closes#2757
Because `io_uring` may have many other I/O submission events queued
(that are relevant to the operation) when we experience an error,
marking our `Completion` objects as aborted is not sufficient, the
kernel will still execute queued I/O, which can mutate WAL or DB state
after we’ve declared failure and keep references (iovec arrays, buffers)
alive and stall reuse. We need to stop those in-flight SQEs at the
kernel and then drain the ring to a known-empty state before reusing any
resources.
The following methods were added to the `IO` trait:
`cancel`: which takes a slice of `Completion` objects and has a default
implementation that simply marks them as `aborted`.
`drain`: which has a default noop implementation, but the `io_uring`
backend implements this method to drain the ring.

If upgrade from read to write transaction fails, don't roll back the
transaction. Instead restore the transaction into its original state,
which allows deferred transactions that have not read anything to
restart automatically.
Fixes#2984Closes#2996
Nikita noticed that database reopen and reconnet cause most database
operations to return "database locked", which means we're not getting
the coverage we need.
- Busy errors do not rollback the transaction
- Transaction takes snapshot of DB state after its first successful
access of the DB, not before its first attempt to access the DB
Previously we were iterating over every entry in the page cache,
clearing the dirty flag from each page.

Incrementally build the frame cache by reading the WAL file in chunks
instead of reading the entire file into memory.

different between output modes is how we handle `Ok(StepResult::Row)` so
let introduce `row_step_result_query` macro to reduce duplicated code.

This PR restructure JS packages and also adds support for OPFS for
tursodatabase in browser.
The new structure looks like this:
1. `@tursodatabase/database-common` - contains abstract JS code for
bindings which depends only on `NativeDB` interface and not on the
explicit native bindings
2. `@tursodatabase/database` - contains native bindings for the database
and re-use `core` package
3. `@tursodatabase/database-browser` - contains bindings for browser
(WASM + OPFS)
As OPFS sync API (which is the most performant one in the web) works
only in the web worker - this PR also make few operations async in order
to run them as `napi-rs` AsyncTask. The following operations became
async in `promise.ts` for node and browser: `pragma` / `exec` / `close`.
Also, as few code pathes during initialization are non-async - they
complicates integration of sync constructor in the browser with OPFS.
So, right now - turso support only `connect` method for browser in non-
memory mode.
Closes#2927
Our current UPDATE/DELETE fuzz tests are coupled to the btree and do not
exercise the VDBE code paths at all, so a separate one makes sense.
This test repeats the following:
- Creates one table with n columns
- Creates (0..=n) indexes
- Executes UPDATE/DELETE statements
- Asserts that both sqlite and tursodb have the same DB state after each
stmt
