Apply pre-sizing optimization to a broader class of objects.
...
Formerly, the length was only fetched from sequence objects.
Now, any object that reports its length can benefit from pre-sizing.

Guido grants a Christmas wish:
...
sorted() becomes a regular function instead of a classmethod.

remain deprecated in the documentation.

* Migrate set() and frozenset() from the sandbox.
...
* Install the unittests, docs, newsitem, include file, and makefile update.
* Exercise the new functions whereever sets.py was being used.
Includes the docs for libfuncs.tex. Separate docs for the types are
forthcoming.

regressing the performance bugfix -- Guido wants the performance bug left
...
alone, because there can be no guarantee re the semantics of += vs + .

Changed builtin_sum to use PyNumber_InPlaceAdd (same semantics, but fixes
...
a performance bug in sum(manylists)), same as in 2.3 maintenance branch.

Simplify and speedup uses of Py_BuildValue():
...
* Py_BuildValue("(OOO)",a,b,c) --> PyTuple_Pack(3,a,b,c)
* Py_BuildValue("()",a) --> PyTuple_New(0)
* Py_BuildValue("O", a) --> Py_INCREF(a)

Fix a crash: when sq_item failed the code continued blindly and used the

NULL pointer. (Detected by Michael Hudson, patch provided by Neal Norwitz).
Fix refcounting leak in filtertuple().

As discussed on python-dev, changed builtin.zip() to handle zero arguments
...
by returning an empty list instead of raising a TypeError.

Some errors from range() should be TypeError, not ValueError.

Prompted by Tim's comment, when handle_range_longs() sees an
...
unexpected type, report the actual type rather than 'float'. (It's
hard to even reach this code with a float. :-)

handle_range_longs(): refcount handling is very delicate here, and
...
the code erroneously decrefed the istep argument in an error case. This
caused a co_consts tuple to lose a float constant prematurely, which
eventually caused gc to try executing static data in floatobject.c (don't
ask <wink>). So reworked this extensively to ensure refcount correctness.

Patch by Chad Netzer (with significant change):
...
- range() now works even if the arguments are longs with magnitude
larger than sys.maxint, as long as the total length of the sequence
fits. E.g., range(2**100, 2**101, 2**100) is the following list:
[1267650600228229401496703205376L]. (SF patch #707427.)
