[gtk+] Remove unused dirty iter discovery functions

[Kristian Rietveld <kristian src gnome org>]

    Remove unused dirty iter discovery functions
    
    gtk_tree_view_discover_dirty_iter() and gtk_tree_view_discover_iter()
    have been in the tree forever, but unused since 1.3.8 or so.  I guess we
    no longer need them, so removed them.  Fixes a compiler warning as well.
