row_move.
* gtk/gtkclist.c (gtk_clist_row_move): new public function.
emit a row_move signal
(real_row_move): move source_row to dest_row
(gtk_clist_swap_rows): use gtk_clist_row_move calls.
(gtk_clist_columns_autosize): resize all columns to their optimal
width
* gtk/gtkctree.c (real_row_move): use gtk_ctree_move to move
entire sub-tree.
* gtk/gtknotebook.c (gtk_notebook_nth_page): get nth page widget.
