        * gtk/gtktreemodelsort.c: more changes in an attempt to get
        it right. It's not yet ready for general consumption.

        * tests/treestoretest.c: add a button and entry for the new
        iter_change function
        (iter_change): new function, to test
        the row_changed signal implementation of the GtkTreeModelSort

        * tests/testtreesort.c: cleanups, changes to test more features
        of the GtkTreeModelSort at once
