Comment:

 * Adds a helper function `_wp_privacy_get_anonymous_user_id()` that
 generates an anonymous user if none exists and return its ID.
   * Returns 0 if no user could be created.
 * Adds a type of `user_id` to the existing `wp_privacy_anonymize_data()`
 helper function to allow easy anonymization of a user ID.

 Questions: How can we prevent logins and wp_admin access by that user by
 all means? I've set the password to `null` and the role to the non-
 existing role `anonymous_user`, but I hope there's a more elegant way to
 achieve this.
