2964225247 Prevent the printf formatter from doing large memory allocations - larger 
than either the size of the static buffer for interfaces like
sqlite3_snprintf(), or larger than SQLITE_LIMIT_LENGTH for interfaces that
are associated with a database connection.  This helps to prevent DOS
attacks on products that let hostile sources inject arbitrary SQL.  It also
helps fuzzers run faster and more effectively.

418454c63f For SQLITE_ENABLE_PREUPDATE_HOOK builds, disable the optimization for a 
REPLACE command on a WITHOUT ROWID table with no indexes, triggers or foreign
key constraints that causes SQLite to clobber any existing row without
separately checking for it. This optimization causes SQLite to omit the
expected pre-update-hook callbacks.
