d4d7042373 Merge 'Use the correct integer PK column idx as the row-id alias' from GV 
This pull request addresses [issue #256](https://github.com/penberg/limbo/issues/256).

However, it currently breaks insertions into tables that lack a row-id
alias due to the NewRowId not being implemented yet. I have created an
[issue](https://github.com/penberg/limbo/issues/275) to track this
problem and will submit a separate pull request to resolve it soon.

Closes #274

31308f3699 core: Switch SQLite to use locking_mode EXCLUSIVE 
Let's switch the SQLite benchmarks to use similar file locking protocol
as we do. Improves SQLite's performance by 2x, but Limbo is still
faster.

Before:

rusqlite/Prepare statement: 'SELECT * FROM users LIMIT 1'
                        time:   [2.1027 µs 2.1239 µs 2.1563 µs]
                        thrpt:  [463.75 Kelem/s 470.83 Kelem/s 475.57 Kelem/s]

After:

rusqlite/Execute prepared statement: 'SELECT * FROM users LIMIT 1'
                        time:   [940.07 ns 944.16 ns 949.39 ns]

145af04c7e Fix serial type decoding for BLOB and TEXT

value `12` is for 0-size BLOB, and `13` is for 0-size TEXT.
