Define H and V widget functions for GTK+3

The horizontal variants are gone from the API.

gtk_rc_get_theme_dir has been deprecated, there is
no replacement so we do the equivalent lookup.

Right-aligned menu items are deprecated.

For now defining gtk_widget_render_icon and
gtk_widget_set_size_request gets rid of warnings.
