Rewrite prng_fortuna.c to much more closely match the description of
Fortuna in chapter 9 of Cryptography Engineering.  Add a facility to
get OS entropy and implement it for Unix and Windows (not yet tested
on Windows) to replace prng/fortuna/entropy.c.  Rewrite the test
harness to always ensure stable output and perform a statistical test
on the predictable internal state resulting from the stable-output
tests.
