Maxheap version of heapq.smallest() is forthcoming.

an alternate algorithm when the number of selected items is small
relative to the full iterable.

* Change a XDECREF to DECREF (adding an assertion just to be sure).

This is basically the support for package data from Phillip Eby's
setuptools package.  I've changed it only to fit it into the core
implementation rather than to live in subclasses, and added
documentation.

Ignore it, rather than breaking.

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.)
