In previous revisions, in every 'do_rounds' loop cycle the 'xperm'

permutation was applied again to convert 32 bit numbers to 48 bit numbers.
Now the 'do_rounds' directly works with 48 bit numbers, and 32 bit
entites are converted on entry and on exit. Effectively, we have now
two 'xperm's and two inverse 'xperm's instead of 16 'xperm's before.
