fixes issue 674 + remove post-call hook for operator delete* since only pre is needed + unfortunately post-call hook is still needed for operatore new*   due to placement new not calling malloc and thus we have to distinguish   "placement new; later direct malloc" and "regular new that calls malloc" + for crt dbg, post-call hook is still needed for operator delete (i#26)
