Update: squeak-3.6

[Marc Espie <espie@nerim.net>]

This is an initial attempt at updating squeak (smalltalk system)
to a more recent version.

I've attached the whole port, since I changed the structure quite a lot.
Specifically, I've put the image and the smalltalk source code into
separate packages.   Things are much simpler, and those packages are
arch-indepedent anyways.

Most of the OpenBSD specific gunk is gone for now, I need to re-evaluate
which of the patches still apply...

This is still !LP64. I don't know how fast they're making progress, there's
definitely an effort to let squeak work on LP64 platforms underways.

Test/comments welcome.
