[gtk+] gtk: Make functions static that don't need to be non-static

[Benjamin Otte <otte src gnome org>]

commit 12683da8f74e847392fff32d4b06dd2c50baa37c
Author: Benjamin Otte <otte redhat com>
Date:   Tue Oct 2 19:23:29 2012 +0200

    gtk: Make functions static that don't need to be non-static
    
    Also remove the starting underscore from function names where
    appropriate, as those functions are static now and not exported anymore.
    
    This is part of a bunch of fixes for gcc complaining about
    -Wmissing-declarations.
