WSAStartup16

[Francois Gouget]

WSAStartup16 seems wrong.
   As I understand it all the Win16 structures have a 1 byte alignment.
Thus the WSASTARTUP structure used by WSAStartup16 should have a 1 byte
alignment. But WSAStartup16 uses the Win32 structure! Why is this
important? Here's why:
 - the last field, lpVendorInfo, will be misaligned
 - the structure will be larger than it should (by 2 bytes). And since
we do a memcpy of sizeof(WSADATA) to the pointer provided by the
application we could have a buffer overflow
 - this creates a dependency between winsock16.h and winsock.h which
greatly bothers me

Or did I miss something?

Changelog:

* include/wine/winsock16.h,
   dlls/winsock/socket.c

Add WSASTARTUP16 a 1 byte alignment version of WSASTARTUP for win16
