Weak Vectors Patch

[Clinton Ebadi]

Attached is a patch that should improve weak vectors and prevent
`vector-ref' from segfaulting on them after a GC.

The root of the problem was that weak vectors were being allocated as
containing no pointers *and* disappearing links were not being
registered for initial elements. If you, however, created an empty weak
vector and then `vector-set!' the elements things were fine.

I'm not sure that weak vectors should have their allocated memory marked
as containing no pointers, but it seems to work so I left that alone in
case there was some magic going on that I didn't quite grok.

CC any replies to me; I'm not subscribed to bug-guile.
