[glib] Add g_simple_async_report_take_gerror_in_idle

commit ba45e36932206f30bb439f27c49529d934207fd1
Author: Christian Persch <chpe gnome org>
Date:   Thu Sep 23 13:47:13 2010 +0200

    Add g_simple_async_report_take_gerror_in_idle
    
    ... and use it where appropriate. Saves an extra GError copy.
    
    Bug #633686.
