bug#15610: 24.3; Implement (network-interface-list) on Windows

[Lubos Pintes <lubos.pintes@gmail.com>]

When I googled about mentioned function, I saw a discussion where
someone stated that it is not possible on Windows for reason I am unable
to remember now.
Now I ran Cygwin version of Emacs and the function is implemented
there. So, it is definitely possible to implement it somehow on Windows.
If not, then please implement it so that it returns nil, or in similar way.
