Make winsock.h and winsock2.h independent from the Unix headers.
Make them compatible with both the Unix C headers and the MSVCRT
headers.
Ensure compatibility with the Unix headers via the USE_WS_PREFIX
macro.
Add WINE_NOWINSOCK: prevents winsock.h from being included from
windows.h when defined.
Add ws2tcpip.h, move definitions to the right header.
