Summary: Restore GC support to set objects

Initial Comment:
Contrary to what the log message for setobject.c 1.26
implies, built-in sets can indeed participate in
cycles, so they must support GC.  This patch restores
GC support to built-in sets for Python 2.4.  It should
be ported to Python 2.5.

Clarification:  cycle.py *as posted* does not demonstrate the 
problem, but if you uncomment the __del__ method in class 
foo, you will get uncollectable garbage.

cycle.py demonstrates the need for this patch

Actually, use set-patch2.txt because I don't believe you
need to clear so->data in set_tp_clear().
