Correction, I just noticed that the four F functions have 4 bit output
not 8 as I wrote. Realize that all this is based on a very cursory
examination of the code.
BTW I just was starting to look at the key scheduling and I noticed that
fullkey is indexed in its 2nd slot by i*2 where i goes from 0 to 31, but
is only declared as being 32 in size in that slot. So I think this is
another typo, probably the index should be i. This kind of thing does
not inspire confidence...
