[glib] Add a preconfigured gio/gnetworking.h for Windows

[Chun-wei Fan <fanchunwei src gnome org>]

commit 4b859e4e7a23e4aaa325770e891b6a73d44cc9fc
Author: Chun-wei Fan <fanchunwei src gnome org>

    Add a preconfigured gio/gnetworking.h for Windows
    
    Since Windows builds by Visual C++ do not make use of autotools during
    its build process, we need to dist a pre-configured
    gio/gnetworking.h(.win32) for such builds.
    
    The vs9/vs10 (and therefore vs11) property sheets are updated as well
