Move MIME DB code back from registrar to src/kits/storage/mime

* Together with database_{access,support}.cpp it is built into a static

* Add new interfaces MimeSniffer and Database::NotificationListener for
  plugging in registrar specific functionality (the sniffer add-on
  support and the notification mechanism).
