b6c5d2e1a6 Cleanup up non-prototyped functions (static) and const-correctness
More fixes based on the compiler directives -Wcast-qual -Wwrite-strings
-Wmissing-prototypes -Wmissing-declarations. Not everything with regards
to -Wcast-qual has been fixed as some have unwanted consequences for the
rest of the code.

3d2dc0f8e5 Corrected GCM counter incrementation to use only 32-bits instead of 128-bits
Using 32-bits has the possibility to overwrite the IV in the first 12
bytes of the Y variable.
