REFARRAY: New referenced array object
    
    This object allows creation the arrays
    with the reference count. Usefull when
    there are many instances of some object
    have to reference dynamically allocated array
    which is common for all these instances.
    
    In case of ELAPI the event object
    keeps a referecne to the common array
    of the sinks in the fail over order.
    
    We decided that it will be a common object
    not specific only to ELAPI.
    
    All the review concerns related to this
    object have been addressed in this patch.
    It also has been moved to the common area.
