[gdk-pixbuf] Support g_autoptr() for all gdk-pixbuf object types

[Kalev Lember <klember src gnome org>]

commit 1c2a984c83d73b11b924894a6bfd50859bd2f6c4
Author: Kalev Lember <kalevlember gmail com>
Date:   Sat Jun 6 20:29:20 2015 +0200

    Support g_autoptr() for all gdk-pixbuf object types
    
    This allows using e.g. g_autoptr(GdkPixbuf) in other programs, but does
    not make gdk-pixbuf itself use g_autoptr, or require a new enough glib
    to support it.
