pickletools:  Import decode_long from pickle instead of duplicating it.

sys.platform != mac.  Likewise expect test_win{reg,sound} to get skipped
on non-win32 platforms.

only get run by test_pickle.py now (& not by test_cpickle.py).  This
should be undone when protocol 2 is implemented in cPickle too.
test_cpickle should pass again.

__getnewargs__ method.

Also tidied up a few lines, got rid of apply(), added a comment.

fails, for reasons unrelated to this patch.

object.__reduce__, do a getattr() on the class so we can explicitly
test for it.  The reduce()-calling code becomes a bit more regular as
a result.

Also add support slots: if an object has slots, the default state is
(dict, slots) where dict is the __dict__ or None, and slots is a dict
mapping slot names to slot values.  We do a best-effort approach to
find slot names, assuming the __slots__ fields of classes aren't
modified after class definition time to misrepresent the actual list
of slots defined by a class.

and also create a symlink "python" pointing to "python$(VERSION)".
Fixes #675745.

start for the C implemention of new pickle LONG1 and LONG4 opcodes (the
linear-time way to pickle a long is to call _PyLong_AsByteArray, but
the caller has no idea how big an array to allocate, and correct
calculation is a bit subtle).

possibility of calling save_reduce().  Add a special hack for this.
The tests for this are much simpler now (no __getstate__ or
__getnewargs__ needed).

Check return value of PyLong_AsDouble(), it can return an error.

checks to save_reduce(), which can also be called from a subclass.)

Also tweaked some more comments.

they're easier to read this way.

of the opcode character instead (but stripping the quotes).

Added a proto 2 test section for the canonical recursive-tuple case.
Note that since pickle's save_tuple() takes different paths depending on
tuple length now, beefier tests are really needed (but not in pickletools);
the "short tuple" case tried here was actually broken yesterday, and it's
subtle stuff so needs to be tested.

I should note that the previous checkin also added NEWOBJ support to
the unpickler -- but there's nothing yet that generates this.
