* Added Lock()/Unlock() for explicit locking by a service user.
* Added NotifyLocked() and made Notify() inline.
* Added HasListeners() so one can check whether there is a listener at all
before preparing the event message.

methods that used an "event mask" field. There was no need to introduce
a "flags" field for the same purpose.
* Renamed protected DefaultNotificationService methods (removed "_" prefix).
* Adjusted the code providing a notification service accordingly.
* Changed the event message several notification services generated by renaming
the "opcode" field to "event".
* Implemented the TEAM_ADDED event and also added a TEAM_EXEC event.
* Added notifications for threads and images.
* Added visitor-like iteration functions for teams, threads, and images.

implementations that can be used by subsystems that want to have a pretty
standard service. Only the latter is really complete, though.
* The notification manager is now available earlier in the boot process.
* Added notifications to teams/ports (only add/remove).
* The network notification implementation is now using the
DefaultUserNotificationService.

* Replaced the use of offsetof() for structs that aren't PODs. Add a
offset_of_member() macro to util/khash.h because that's what it's used for
in our cases.
* Change the signature of add_debugger_command()/remove_debugger_command() on
GCC > 2 to avoid the depricated conversion from string constants to char *.
* Adding some "suggested" parenthesis. I know that not everyone likes that, but
it pointed out at least one bug that is fixed here as well.

always returned B_OK) by a Init() method, which sets the initial size
and returns an error, if that fails.
* Adjusted code using the classes accordingly. Replaced a few
InitCheck() methods in the network code by Init().

* Trivial adjustments of code using mutexes. Mostly removing the
mutex_init() return value check.
* Added mutex_lock_threads_locked(), which is called with the threads
spinlock being held. The spinlock is released while waiting, of
course. This function is useful in cases where the existence of the
mutex object is ensured by holding the threads spinlock.
* Changed the two instances in the VFS code where an IO context of
another team needs to be locked to use mutex_lock_threads_locked().
Before it required a semaphore-based mutex implementation.

* 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.

Will be used for node monitoring and other stuff, too (like the Registrar or the
VM low memory handler).
