MINOR Moved SQLite3Database::safe_dir() to two new methods on SQLite3DatabaseConfigurationHelper (create_db_dir() and secure_db_dir()), more flexible and useable from the helper class in install.php context without requiring class inclusions pre-manifest build (see r101054 for installer enhancements)
