        Refactor GtkFileChooserDialog sizing.

        * gtkfilechooserembed.[ch] (delegate_get_resizable_hints)
        (_gtk_file_chooser_embed_get_resizable_hints):
        s/resizable_hints/resizable/, return just one boolean value to
        determine whether the filechooser should be resizable or not.

        * gtkfilechooserprivate.h (struct GtkFileChooserDialogPrivate): remove
        variables related to the GtkFileChooserEmbed get_default_size() and
        get_resizable() implementations.
        (struct GtkFileChooserDefault): Move default size management here.

        * gtkfilechooserdefault.c (gtk_file_chooser_default_size_allocate):
        Added, store currently allocated size to calculate default size later.
        (gtk_file_chooser_default_get_resizable_hints):
        s/resizable_hints/resizable/.
        (gtk_file_chooser_default_set_property): Reload settings if the file
        chooser action changes, this way the save expander state will be known
        before mapping the window, avoiding wrong window positioning and
        flickering. (#424299, #424309)
        (find_good_size_from_style): Only get size from style if it wasn't set
        previously.
        (gtk_file_chooser_default_get_default_size): return default size based
        on stored default size and preview/extra widget sizes.

        * gtkfilechooserdialog.c (file_chooser_widget_update_hints)
        (file_chooser_widget_realized_size_changed)
        (file_chooser_widget_unrealized_size_changed): simplified to
        (file_chooser_widget_size_changed): set window size and resizability
        based on the GtkFileChooserEmbed interface implementation. (Bug
        #420285, Tomeu Vizoso)
        (gtk_file_chooser_dialog_map): force a dialog size change, so it's
        clamped for sure to the 75% of the screen size.
