[gtk+] Use _GDK_EXTERN when defining the decorators

[Matthias Clasen <matthiasc src gnome org>]

commit 9c0486a7269e272411b8d5ec66ceb0112c236bb6
Author: Matthias Clasen <mclasen redhat com>

    Use _GDK_EXTERN when defining the decorators
    
    Make all GDK_DEPRECATED and GDK_AVAILABLE macros use a
    new _GDK_EXTERN macro. _GDK_EXTERN defaults to just 'extern'
    but a subsequent commit will add visibility handling to it
    while building GTK+.
