Remove gdk_surface_set_user_data

Browse Source 
Change gdk_surface_get/set_user_data to private
API and rename them to get/set_widget.
Also remove an unused associated function.

The last two places where the surface API is used
are in gtkroot.c and gtkwidget.c. Make them
use the private api.

/**
* gdk_surface_set_user_data:
* @surface: a #GdkSurface
* @user_data: (allow-none) (type GObject.Object): user data
*
* For most purposes this function is deprecated in favor of
* g_object_set_data(). However, for historical reasons GTK+ stores
* the #GtkWidget that owns a #GdkSurface as user data on the
* #GdkSurface. So, custom widget implementations should use
* this function for that. If GTK+ receives an event for a #GdkSurface,
* and the user data for the surface is non-%NULL, GTK+ will assume the
* user data is a #GtkWidget, and forward the event to that widget.
