3ecdb250af Fix for bug #966623 - classes created with type() in an exec(, {}) don't 
have a __module__. Test for this case.

Bugfix candidate, will backport.

c978633ec6 Futher improvements to frozenset hashing (based on Yitz Gale's battery of 
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.

27e403ebe9 Fixups to the hash function for frozensets. 
* 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.

57c2d930f6 Add a final permutation step to the tuple hash function. 
Prevents a collision pattern that occurs with nested tuples.
(Yitz Gale provided code that repeatably demonstrated the weakness.)

4ec44e851d Replaced arbitrary addend in tuple_hash with one that is known to generate 
many more prime multipliers and that performs well on collision tests.

974ed7cfa5 - SF #962502: Add two more methods for unicode type; width() and 
iswide() for east asian width manipulation. (Inspired by David
Goodger, Reviewed by Martin v. Loewis)
- Move _PyUnicode_TypeRecord.flags to the end of the struct so that
no padding is added for UCS-4 builds. (Suggested by Martin v. Loewis)

steps and further improves the speed of list append.

* Add guards to the list iterator length method to handle corner cases.

4e10ed3b86 If a file is opened with an explicit buffer size >= 1, repeated 
close() calls would attempt to free() the buffer already free()ed on
the first close().     [bug introduced with patch #788249]

Making sure that the buffer is free()ed in file object deallocation is
a belt-n-braces bit of insurance against a memory leak.

56716150e6 This is the fastest I could get on Intel GCC. I kept the memset() in to clear 
the newly created tuples, but tuples added in the freelist are now cleared in
tupledealloc already (which is very cheap, because we are already
Py_XDECREF'ing all elements anyway).

Python should have a standard Py_ZAP macro like ZAP in pystate.c.

5f112eb43b recursive_isinstance(), recursive_issubclass(): New code here returned 
NULL in case of error, but the functions are declared to return int.
MSVC 6 properly complains about that.  Return -1 on error instead.
