When we had multiple sql statements in cli/interactive shell, we were
only running one from them as shown below. This PR fixes them.
One added benefit of this is we can add complex sql in the tcl test
files like the changes in insert.test .

@PThorpe92 I don't think we need the `parent_op` machinery at all, we
just need to not jump to the `jump_target_when_true` label given by the
parent if we are evaluating the first condition of an AND.

This PR adds the `load_extension` function, and allows for platform
agnostic arguments: e.g. `select
load_extension('target/debug/liblimbo_uuid');` omitting the file
extension.

While working to include new json functions (related to #127) I noticed
that the program step code for json functions https://github.com/tursoda
tabase/limbo/blob/0dceb02ec04241b3772332853bcbfb9eb559adb9/core/vdbe/mod
.rs#L1346 was a bit different from scalar functions's code, where the
match to the inner function is nested https://github.com/tursodatabase/l
imbo/blob/0dceb02ec04241b3772332853bcbfb9eb559adb9/core/vdbe/mod.rs#L142

I added the same nesting to the json functions so it is more consistent

This shaves off `nix` as a dependency in core, which was only being used
in the io_uring backend for the `fcntl` advisory record locking. Since a
previous PR made `rustix` a dep not only for Mac but for any Unix, and
`rustix` also has `fcntl`, `nix` becomes redundant.
Furthermore, it reduces `libc` usage across core. The only remaining
uses are:
```rust
io_uring::opcode::Readv::new(fd, iovec as *const iovec as *const libc::iovec, 1)
io_uring::opcode::Writev::new(fd, iovec as *const iovec as *const libc::iovec, 1)
```
These two are a little ugly, but sadly the `io_uring` crate requires
both opcodes to take a `libc::iovec` while it doesn't export the type.
See tokio-rs/io-uring#259 for a request to use `std::io::IoSlice` or to
export the type directly.
Apart from those two, there are no other usages of libc, so if those are
resolved, we could also drop the dependency on libc.

seeing #660 made me realize I shouldn't have used `now` in any
circumstances in these tests, tolerance or not ;)
they should all be deterministic now

This PR fixes#666
Limbo was treating all single byte integers properly in `core/types.rs`,
but when converted in `sqlite3_ondisk`, it was losing the sign for 8 bit
integers, treating them all as unsigned. Sqlite3 specifies in their file
format that the `1` record serial type is "Value is an 8-bit twos-
complement integer." https://www.sqlite.org/fileformat.html
We now properly match sqlite3's output
Closes#667
Give the user the option of choosing IO backend. There is only a
"syscall" backend, unless built for Linux with `#[cfg(feature =
"io_uring")]` which introduces `--io=io-uring`.
Right now, the choice has only been implemented for the CLI. Bindings
and such default to PlatformIO, except when an "in-memory" database has
been chosen.
Can be tested by running CLI with RUST_LOG=debug
