user-notification: 'productify' the user-warning system

* Rename user_warning to user_notification
* Add warning and error types (in addition to the existing deprecated)
* Simplify logic when emitting a user notification after forking; we
  don't need to copy the notification data since we're in a new
  process and have total control over that memory.
