On Windows, it is sometimes problematic to depend on ws2_32.dll. Before, users of std.Io.Threaded would have to call ioBasic() rather than io() in order to avoid unnecessary dependencies on ws2_32.dll. Now, the application can disable networking with std.Options. This change is necessary due to moving networking functionality to be based on Io.Operation, which is a tagged union.
