* eventhandler.h: Handle registration of event handlers

* This is a facility in the NT server to provide a way to register event
* handling functions. Often there is a need to send a control signal of some

* logs, or a signal to collect and return statistical information of some kind
* such as perfmon stats.
*
* This file specifies the structures and functions necessary to set up this
* kind of asynchronous special event handling.
