    * subr.el (with-selected-window): Preserve the selected window's
    terminal's top-frame.
    * window.el (save-selected-window): Likewise.
    * frame.c (delete_frame): When selecting a frame on a different
    text terminal, do not alter the terminal's top-frame.
    * term.c (Ftty_top_frame): New function.
    * xdisp.c (format_mode_line_unwind_data): Record the target
    frame's selected window and its terminal's top-frame.
    (unwind_format_mode_line): Restore them.
    (x_consider_frame_title, display_mode_line, Fformat_mode_line):
    Callers changed.
    (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
    since tty frames can be explicitly named.
    (prepare_menu_bars): Likewise.
