-CreateCallbackList creates a callback list.  We envision that this

-automatically (if it doesn't already exist) when the first call to
-AddCallback is made on the list.  The only reason to explicitly create
-the callback list with this function is if you want to override the
-implementation of some of the other operations on the list by passing
-your own cbfuncs.  You also lose something by explicit creation: you
-introduce an order dependency during server startup because the list
-must be created before any modules subscribe to it.  Returns TRUE if
