[gobject-introspection] Better scope in GAsyncReadyCallback/GDestroyNotify

commit f74823dbcb647dee950c066119876db9f0edc32f
Author: Johan Dahlin <johan gnome org>
Date:   Tue Nov 24 22:18:27 2009 -0200

    Better scope in GAsyncReadyCallback/GDestroyNotify
    
    GAsyncReadyCallback should have use the async scope per
    default and GDestroyNotify should be notified if the
    previous parameters are a callback and user data.
    
    Fixes https://bugzilla.gnome.org/show_bug.cgi?id=602862
