Bug fixes:
1. Fix a problem in REPLACE that can result in a corrupt database
containing two or more rows with the same rowid.
2. Fix a problem in PRAGMA integrity_check that was causing a subsequent
VACUUM to behave suboptimally.
3. Fix the PRAGMA foreign_key_check command so that it works correctly with
foreign keys on WITHOUT ROWID tables.
4. Disallow leading zeros in numeric constants in JSON.
5. Disallow control characters inside of strings in JSON.
6. Limit the depth of recursion for JSON objects and arrays in order to
avoid excess stack usage in the recursive descent parser.
7. Fix more bugs in the LEFT JOIN flattening optimization.
