    Gtk::Assistant, etc.: Fix bugs noticed by clang++
    
    * gtk/src/assistant.hg:
    * gtk/src/notebook.hg:
    * gtk/src/stack.hg: get_page() shall not be declared constversion.
    The const version is not identical to the non-const version.
    * gtk/src/mediacontrols.hg:
    * gtk/src/video.hg: set_media_stream() shall not be declared
    refreturn, constversion. It's not const. It does not return a value.
    * tools/m4/convert_gtk.m4: Declare some new _CONVERSION()s.
