Remove weakref free list. This has the side effect of fixing a memory
...
management bug. Also, move some duplicated code into the new_weakref
fucntion.

both are proxy objects.

Make sure that when we invoke callback functions associated with weak
...
references, we do not allow any outstanding exceptions "leak" into the
callback's execution state.
This closes SF bug #478534 .

When weakref proxies are involved in binary & ternary slot operations,
...
the left-hand operand may not be the proxy in all cases. If it isn't,
we end up doing two things: a) unwrapping something that isn't a
PyWeakReference (later resulting in a core dump) and b) passing a
proxy as the right-hand operand anyway, even though that can't be
handled by the actual handler (maybe eventually causing a core dump).
This is fixed by always unwrapping all the proxies involved before
passing anything to the actual handler.
