native-layout: Introduce GtkExtendedLayout interface.

/* GTK - The GIMP Toolkit
Mega commit backing out everything from the native-layout branch that is not ready for integration This commit makes the native-layout branch into a reasonable patch applicable to git master, it pulls out GtkCellRenderer support, ComboBox support, the Plug/Socket api is also not ready and is pulled out.

Added gtk_extended_layout_is_height_for_width() Added an indicator telling whether a widget prefers to be allocated as height-for-width or width-for-height. Usually this depends on the orientation of a container or the nature of a content widget like GtkLabel. This indicator is only used in the seldom case where a parent is allocating free space to the child and the child can flow in either direction, GtkWindow and GtkScrolledWindow are users of this api.

gboolean (* is_height_for_width) (GtkExtendedLayout *layout);
Mega commit to change ->get_desired_size() for ->get_desired_width/height(). This commit changes gtk_extended_layout_get_desired_size() for per dimension variants. Furthermore this commit reverts the actions done in size-groups for now as it needs a different approach. The natural width/height parameters added to aux_info have been changed for a per width cache for heights and a per height cache for widths. gtk-demo is still working, currently sizegroups are not taken into account as mentioned above - size groups need to be alerted both when the widths and heights are updated independantly and then that information needs to repropagate also to other extended layout implementors.
