* 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. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21780 a95241bf-73f2-0310-859d-f6bbb57e9c96
