Upgrade from Winsock 1.1 to Winsock 2.2, which is always available on Win2000+. See: [http://msdn.microsoft.com/en-us/library/windows/desktop/ms742213%28v=vs.85%29.aspx] for details.

Move winsock initialization to TclpInitPlatform(void), so we can be sure everywhere that we have an initialized winsock2. 
Stub entries for TclWinGetServByName/TclWinGetSockOpt/TclWinSetSockOpt are no longer necessary (will be removed in 9.0, but are kept in 8.x)
