socks & wine, patching wininet to use winsock

I was thinking about looking at wininet soon myself, but haven't had
the time. I don't know what the right approach should be, but the
least I can tell you is stop including all the linux headers:

# include <netdb.h>
# include <sys/types.h>
# include <netinet/in.h>
# include <sys/socket.h>

Then you want to include the winsock headers and change to
stop linking with @SOCKETLIBS@ and instead link with ws2_32. Make sure
to run configure again after doing that. After that get to fixing
warnings about SOCKET/int conversion and various crashes :)
