[glib] gdbus: Use g_markup_collect_known_attributes() in GDBus introspection

[Matthias Clasen <matthiasc src gnome org>]

commit 86329ba44fc7662c0bad37955f0ec980a24be495
Author: Matthias Clasen <mclasen redhat com>
Date:   Thu Aug 16 23:41:19 2012 -0400

    gdbus: Use g_markup_collect_known_attributes() in GDBus introspection
    
    In order to be able to cope with the introspection XML
    from the Telepathy specification, which uses attributes
    like tp:type and tp:name-for-bindings, we need to ignore
    unknown attributes when parsing.
    Closes: https://bugzilla.gnome.org/show_bug.cgi?id=665634
