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.
