Axel Dörfler edb15b5565 bonefish+axeld:
* Simplified the notification framework: removed the updater stuff completely;
  it was only there to account for some peculiarities of the node monitor which
  we now solved differently.
* NotificationListener no longer includes a doubly linked list link for convenience;
  it might want to listen to more than just one service.
* NotificationService cannot have an abstract destructor.
* Changed the _user_stop_watching() syscall to mirror the Be API; ie. it's no
  longer possible to just remove some flags separately, just to stop listening
  completely.
* Adapted the node monitor implementation to live in the NodeMonitorService class
  that uses the new notification framework.
* Removed the public kernel node monitor API - it wasn't useful that way since you
  couldn't do a lot with the KMessage in the kernel without using a private API.
  Now you will have to use the (private) notification manager to use the node monitor
  from inside the kernel. At a later point, we might introduce a public API for that,
  too.
