The code has been modularized so that it can be shared by algorithms. A fixed size IV is now used instead of being allocated. The IV is not set into the low level struct now until the update (it uses an iv_state for this purpose). Hardware specific methods have been added to a PROV_GCM_HW object. The S390 code has been changed to just contain methods that can be accessed in a modular way. There are equivalent generic methods also for the other platforms.
