Extend SQLiteQueryBuilder for update and delete.

Developers often accept selection clauses from untrusted code, and
SQLiteQueryBuilder already supports a "strict" mode to help catch
SQL injection attacks.  This change extends the builder to support
update() and delete() calls, so that we can help secure those
selection clauses too.
