tests which nicely highly highlight weaknesses).

* Initial value is now a large prime.
* Pre-multiply by the set length to add one more basis of differentiation.
* Work a bit harder inside the loop to scatter bits from sources that
  may have closely spaced hash values.

All of this is necessary to make up for keep the hash function commutative.
Fortunately, the hash value is cached so the call to frozenset_hash() will
only occur once per set.

* Non-zero initial value so that hash(frozenset()) != hash(0).
* Final permutation to differentiate nested sets.
* Add logic to make sure that -1 is not a possible hash value.

Prevents a collision pattern that occurs with nested tuples.
(Yitz Gale provided code that repeatably demonstrated the weakness.)

This fixes the problem and the test passes.  I'm not sure
the test is really correct though.  It seems like it would
be better to raise an exception.  I think that wasn't done
for backwards compatability.

Bugfix candidate.

This is similar to test_normalization, so that many source trees
can reference the same test file(s).

Document that it can't be done on Windows.
