__delitem__, __setslice__ and __delslice__ hooks. This caused test_weakref
and test_userlist to fail in the p3yk branch (where UserList, like all
classes, is new-style) on amd64 systems, with open-ended slices: the
sys.maxint value for empty-endpoint was transformed into -1.

Barry approved it awhile ago.  Been sitting in my sandbox for awhile as
well.

- tp_new (which was apparently always overridden:-) called base class
  tp_init in stead of tp_new.

Add some items; add "New module" consistently; make contextlib.closing example more interesting and more correct (thanks Gustavo!); add a name

I tested this with valgrind on amd64.

The man pages I found for diff architectures are inconsistent on this.
I'm not entirely sure this change is correct for all architectures either.

Perhaps we should just over-allocate and not worry about it?

case.  I've yet to figure out how to provoke a None return I can test.

was having funny effects when called on >2Gb strings ;P

zfill stringmethods, so they can create strings larger than 2Gb on 64bit
systems (even win64.) The unicode versions of these methods already did this
right.

Write datetime.strptime() item; show use of @contextmanager in defining __context__ methods; minor edits; add two names

abstract namespace that is now fully supported.

Handy to have as a separate rule from clean when mucking around with bytecode
generation.

the StgDictObject's ffi_type member had the same name as its type.  I
changed that to ffi_type_pointer.  Feel free to change it to something else
more meaningful, just not ffi_type.

Fixes [ 1465834 ] bdist_wininst preinstall script support is broken in 2.5a1.

``get_build_platform()`` to work around a Mac versioning problem that caused
the behavior of ``compatible_platforms()`` to be platform specific.

This makes 'import ctypes; reload(ctypes)' no longer leak reference counts.

Python code can mangle with mp->ma_smalltable while it is being walked
over.
