Log message:
        Make (many) trivial substitutions for renamed and
        new macros in dispextern.h, frame.h and window.h.
        (make_window): Initialize new members
        left_margin_cols, right_margin_cols, left_fringe_width,
        right_fringe_width, fringes_outside_margins, scroll_bar_width,
        and vertical_scroll_bar_type.
        (coordinates_in_window): Adapted to new fringe/margin positions
        and per-window fringes and scroll-bars.
        Fix bug related to incorrectly adjusting coordinates by
        frame's internal_border_width (the effect normally negible since
        the internal_border_width is typically 0 or 1 pixel, but very
        noticeable for an internal_border_width of e.g. 25 pixels).
        Upon successful return (other than ON_NOTHING), the coordinates
        are now always properly converted to window relative for the
        given display element.
        (window_from_coordinates): Add new parameters wx and wy to
        return the window relative x and y position in the returned
        window and part.  A null arg means, don't return the position.
        All callers changed.
        (adjust_window_margins): New function which may reduce the width
        of the display margins if a window's text area is too small after
        resizing or splitting windows.
        (size_window): Fix bug that did not account for display margin
        widths when checking the minimum width of a window; use
        adjust_window_margins.
        (set_window_buffer): Call Fset_window_fringes and
        Fset_window_scroll_bars to setup per-window elements.
        Add new arg KEEP_MARGINS_P.  Non-nil means to keep window's
        existing display margin, fringe widths, and scroll bar settings
        (e.g. after splitting a window or resizing the frame).  All
        callers changed.
        (Fset_window_buffer): New arg KEEP_MARGINS.  All callers changed.
        (Fsplit_window): Duplicate original window's display margin,
        fringe, and scroll-bar settings; then call Fset_window_buffer with
        KEEP_MARGINS non-nil.  This fixes a bug which caused a split
        window to only preserve the display margins in one of the windows.
        When splitting horisontally, call adjust_window_margins on both
        windows to ensure that the text area of the new windows is non too
        narrow.  This fixes a bug which could cause emacs to trap if the
        width of the split window was less than the width of the display
        margins.
        (window_box_text_cols): Renamed from window_internal_width.  All
        uses changed.  Adapt to per-window fringes and scroll bars.
        Fix bug that caused vertical separator to be subtracted also on
        window frames.  Fix another bug that did not reduce the returned
        value by the columns used for display margins.
        (window_scroll_line_based): Fix bug related to scrolling too much
        when display margins are present (implicitly fixed by the fix to
        window_box_text_cols).
        (scroll_left, scroll_right): Fix bug related to scrolling too far
        by default when display margins are present (implicitly fixed by
        the fix to window_box_text_cols).
        (struct saved_window): Rename members left to left_col, top to
        top_line, width to total_cols, height to total_lines, orig_top to
        orig_top_line, orig_height to orig_total_lines.  All uses changed.
        New members left_margin_cols, right_margin_cols,
        left_fringe_width, right_fringe_width, fringes_outside_margins,
        scroll_bar_width, and vertical_scroll_bar_type for saving
        per-window display elements.
        (Fset_window_configuration): Restore display margins, fringes,
        and scroll bar settings.  This fixes a bug which caused display
        margins to be discarded when saving and restoring a window
        configuration.
        (save_window_save): Save display margins, fringes, and scroll bar
        settings.  This fixes a bug which caused display margins to be
        discarded when saving and restoring a window configuration.
        (Fset_window_margins): Do nothing if display margins are not
        really changed.  Otherwise, call adjust_window_margins to ensure
        the text area doesn't get too narrow.  This fixes a bug which
        could cause emacs to trap if setting display margins wider than
        the width of the window.
        (Fset_window_fringes): New defun to allow user to specifically set
        this window's fringe widths and position vs. display margins.
        (Fwindow_fringes): New defun to return window's actual fringe
        settings.
        (Fset_window_scroll_bars): New defun to allow user to specifically
        set this window's scroll bar width and position.
        (Fwindow_scroll_bars): New defun to return window's actual scroll
        bar settings.
        (compare_window_configurations): Also compare display margins,
        fringes, and scroll bar settings.
        (syms_of_window): Defsubr new defuns for fringe and scroll bars.
