Preliminary support.  What's here works, but needs fine-tuning.

Andrew quite correctly notices that the next() method isn't quite what
we need, since it returns None upon end instead of raising
StopIteration.  His fix is easy enough, using iter(self.next, None)
instead.

because they don't work yet.

backwards compatibility.  When using the class of the first base as
the metaclass, use its __class__ attribute in preference over its
ob_type slot.  This ensures that we can still use classic classes as
metaclasse, as shown in the original "Metaclasses" essay.  This also
makes all the examples in Demo/metaclasses/ work again (maybe these
should be turned into a test suite?).

Inhibited complex unary plus optimization when applied to a complex subtype.
Added PyComplex_CheckExact macro.  Some comments and minor code fiddling.

errors occur.)

with the same value instead.  This ensures that a string (or string
subclass) object's ob_sinterned pointer is always a str (or NULL), and
that the dict of interned strings only has strs as keys.

+ These were leaving the hash fields at 0, which all string and unicode
  routines believe is a legitimate hash code.  As a result, hash() applied
  to str and unicode subclass instances always returned 0, which in turn
  confused dict operations, etc.

subclasses, all "the usual" ones (slicing etc), plus replace, translate,
ljust, rjust, center and strip.  I don't know how to be sure they've all
been caught.

Question:  Should we complain if someone tries to intern an instance of
a string subclass?  I hate to slow any code on those paths.
