solution.

PyTypeObject structures, I had to make prototypes for the functions, and
move the structure definition ahead of the functions. I'd dearly like a better
way to do this - to change this would make for a massive set of changes to
the codebase.

There's still some warnings - this is purely to get rid of errors first.

malloc/realloc type functions, as well as renaming one variable called 'new'

chunk at a time or the patch will be massively huge. Still compiles ok with
gcc.

"x86 OpenBSD trunk" buildbot due to changing Python so that
Python-exposed addresses are always non-negative.

test_int_pointer_arg():  This line failed now whenever the
box happened to assign an address to `ci` "with the sign
bit set":

    self.failUnlessEqual(addressof(ci), func(byref(ci)))

The problem is that the ctypes addressof() inherited "all
addresses are non-negative now" from changes to
PyLong_FromVoidPtr(), but byref() did not inherit that
change and can still return a negative int.

I don't know whether, or what, the ctypes implementation wants
to do about that (possibly nothing), but in the meantime
the test fails frequently.

So, introduced a Python positive_address() function in
the test module, that takes a purported machine address and,
if negative, converts it to a non-negative value "with the
same bits".  This should leave the test passing under all
versions of Python.

Belated thanks to Armin Rigo for teaching me the sick trick ;-)
for determining the # of bits in a machine pointer via abuse
of the struct module.

tests.  Alas, because only the "x86 OpenBSD trunk" buildbot fails
these tests, and test_descr stops after the first failure, there's
no sane way for me to fix these short of fixing one and then
waiting for the buildbot to reveal the next one.

failing on one of the 32-bit buildbot boxes because of it,
due to tempting but always-wrong Python code.  Users
probably have code like this too (I know I did ...).

__hash__, although there's nothing to check there beyond
that they don't blow up.

to that id() can now return a Python long on a 32-bit box that allocates
addresses "with the sign bit set".

test_set.py test_subclass_with_custom_hash():  it's never been portably
legal for a __hash__() method to return id(self), but on 32-bit boxes
that never caused a problem before it became possible for id() to
return a Python long.  Changed __hash__ here to return a Python int
regardless of platform.

test_descr.py specials():
    vereq(hash(c1), id(c1))
has never been a correct test -- just removed it (hash() is always
a Python int; id() may be a Python long).

due to that id() may return a long on a 32-bit box now.  On a box that
assigns addresses "with the sign bit set", id() always returns a long now.

that are suspended outside of any try/except/finally blocks to be
garbage collected even if they are part of a cycle.  Generators that
suspend inside of an active try/except or try/finally block (including
those created by a ``with`` statement) are still not GC-able if they
are part of a cycle, however.

Introduce _child_active member to keep track on whether a child
