[gtk+] let the close button reflect the page_complete status of SUMMARY pages

[Sven Herzberg <herzi src gnome org>]

commit 70440523e3d92fd6e1a228c176e4e700012b4ba0
Author: Sven Herzberg <herzi gnome-de org>
Date:   Thu Dec 10 17:34:29 2009 +0100

    let the close button reflect the page_complete status of SUMMARY pages
    
    Fixes: https://bugzilla.gnome.org/show_bug.cgi?id=604289
    In order to respect this properly, we have to restore the original
    behavior by watching a flag to check if the user has already set this.
    
    * gtk/gtkassistant.c: fix the bug by introducing a flag to check for
      non-automatic value setting
    * tests/testassistant.c: updated the "generous assistant" to permit
      quick manual testing of this feature
