    Paths: bring some path normalization operations between platforms
    
    These operations are being used in Banshee's playlist code currently,
    but it makes more sense to encapsulate them as functions and leave them
    in the Hyena.Paths namespace, in a similar way as Paths.MakePathRelative()
    which is also used in the same class.
