Make Emacs compile when Gtk+ and -DGTK_DISABLE_DEPRECATED is used.

* gtkutil.c (xg_tool_bar_menu_proxy, update_frame_tool_bar): Use
G_CALLBACK instead of GTK_SIGNAL_FUNC which is deprecated.
(xg_initialize): Use g_type_class_ref instead of gtk_type_class which
is deprecated.

* configure.in (HAVE_GTK_FILE_SELECTION, HAVE_GTK_FILE_CHOOSER): Check
if it is declared in gtk.h.
