Provide a DB fallback for keys in wp_salt(). Fall back when any secret is used more than once. Change how we detect a localized 'put your unique phrase here' -- eliminate $wp_default_secret_key and introduce $wp_secret_key_default to be added during the localized build process, not by translators. fixes #19599.
