    This way, we can support external libraries providing implementations of
    GtkMediaFile.
    
    We also add a media backend called 'nomedia' that can be enabled to not
    compile any support for GtkMediaFile. This is useful when people want to
    statically compile GTK into an application that does not use media.
    For now, this option is the default.
    
    We also support a new environment variable GTK_MEDIA that allows
    selecting the implementation to use.
    GTK_MEDIA=help can be used to get info about the available
    implementations.
