    * window.h (struct window): Replace hchild, vchild and buffer slots · e74aeda8

    with the only contents slot.  This is possible because each valid
    window may have either the child window (in vertical or horizontal
    combination) or buffer to display (for the leaf window).  Using that,
    a lof of operations to traverse and/or change window hierarchies may
    be simplified.  New member horizontal is used to distinguish between
    horizontal and vertical combinations of internal windows.
    (WINDOW_VALID_P, WINDOW_LIVE_P): Adjust to match struct window changes.
    * window.c (wset_hchild, wset_vchild): Remove.  Adjust all users.
    Use contents slot, not buffer, where appropriate.
    (wset_combination): New function.
    (wset_buffer): Add eassert.
    (Fframe_first_window): Simplify the loop reaching first window.
    (Fwindow_buffer): Use WINDOW_LEAF_P.
    (Fwindow_top_child): Use WINDOW_VERTICAL_COMBINATION_P.
    (Fwindow_left_child): Use WINDOW_HORIZONTAL_COMBINATION_P.
    (unshow_buffer): Convert initial debugging check to eassert.
    (replace_window, recombine_windows, Fdelete_other_windows_internal)
    (make_parent_window, window_resize_check, window_resize_apply)
    (resize_frame_windows, Fsplit_window_internal, Fdelete_window_internal)
    (Fset_window_configuration, delete_all_child_windows, save_window_save):
    Adjust to match struct window changes.
    (window_loop): Check for broken markers in CHECK_ALL_WINDOWS.
    (mark_window_cursors_off, count_windows, get_leaf_windows)
    (foreach_window_1): Simplify the loop.
    * alloc.c (mark_object): Do not check for the leaf window because
    internal windows has no glyph matrices anyway.
    * dispnew.c (clear_window_matrices, showing_window_margins_p)
    (allocate_matrices_for_window_redisplay, fake_current_matrices)
    (allocate_matrices_for_frame_redisplay, free_window_matrices)
    (build_frame_matrix_from_window_tree, mirror_make_current)
    (frame_row_to_window, mirror_line_dance, check_window_matrix_pointers)
    (update_window_tree, set_window_update_flags): Simplify the loop.
    (sync_window_with_frame_matrix_rows): Enforce live window.
    Use contents slot, not buffer, where appropriate.
    * frame.c (set_menu_bar_lines_1): Use WINDOW_VERTICAL_COMBINATION_P
    (make_frame_visible_1): Simplify the loop.
    Use contents slot, not buffer, where appropriate.
    * xdisp.c (hscroll_window_tree, mark_window_display_accurate)
    (redisplay_windows, redisplay_mode_lines, update_cursor_in_window_tree)
    (expose_window_tree): Likewise.
    Use contents slot, not buffer, where appropriate.
    * textprop.c (get_char_property_and_overlay): Add CHECK_LIVE_WINDOW
    to avoid deleted windows.  Use contents slot instead of buffer.
    * buffer.c, dispextern.h, editfns.c, fileio.c, font.c, fringe.c:
    * indent.c, insdel.c, keyboard.c, keymap.c, minibuf.c, msdos.c:
    * nsfns.m, nsmenu.m, nsterm.m, print.c, w32fns.c, w32menu.c, xfaces.c:
    * xfns.c, xmenu.c: Use contents slot, not buffer, where appropriate.
