9e8dd45164 notifier: Pass data argument to callback 
This allows to pass additional information to the notifier callback
which is useful if sender and receiver do not share any other distinct
data structure.

Will be used first for the clock reset notifier.

d1e70c5e6d Add support for generic notifier lists 
Notifiers are data-less callbacks and a notifier list is a list of registered
notifiers that all are interested in a particular event.

We'll use this in a few patches to implement mouse change notification.
