        * gobject.[ch] gobject.symbols: Add
        g_object_add/remove_toggle_ref() functions to get notification
        when a reference count is the last remaining reference; this
        enables better memory management for language bindings.

        * glib/gdataset.[ch] glib/gdatasetprivate.h: Add
        g_datalist_set/unset_flags(), g_datalist_get_flags() functions
        to squeeze some bits into a GDataSet... this is needed for
        efficient implementation of toggle references in GObject.

        * tests/gobject/references.c tests/gobject/Makefile.am:
        Add a test case for weak and toggle references.

        * glib/gfileutils.[ch]: Rename g_file_replace() back
        to g_file_set_contents().

        * glib/glib.symbols: Update.

        * gobject/tmpl/objects.sgml: Document toggle-references.
