> 
> This is the first patch of a series that is designed to enable the Direct Rules
> API.
> 
> The main difference between Direct Verbs and Direct Rules from API
> prespective, is that in Direct Rules each action has it's own create function
> and the object itself is of type void.
> 
> In this patch I'm adding functions to generate actions that currenlty are done
> without create action, and I'm changing the action type to be void *, so in
> next patches only the glue functions will need to change.
