Slony under win32

I created new makefiles for slony_funcs and xxid using the contrib 
infrastructure, which makes them win32 compatible. IMHO the attached 
versions should replace the current ones.

After some short tests, Slony-q 1.0.5 seems to be able to replicate with 
win32 servers using those modules correctly.

The slon process currently refuses to link, the thread lib seems to be 
the problem.

Apparently slonik uses fork(), which would make porting it much more 
expensive. I won't spent more time on that, pgAdmin will do that anyway.
