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.
