winsock2 unit test update

A patch for the winsock 2 unit test posted yesterday.
It now has an overlapped client. If you look at the code,
it does pretty nasty things to wine, and still works :-)
BUGS: probably doesn't compile under Windows, I'm using some
gcc extensions. You just get too used to them ...
If somebody was able to port these to Windows and test the outcome I
would be really happy.
