Make scrollbar structures into lisp objects, so that they can be
GC'd; this allows windows and scrollbars can refer to each other without worrying about dangling pointers. * xterm.h (struct x_display): vertical_scrollbars and judge_timestamp members deleted. (struct scrollbar): Redesigned to be a template for a Lisp_Vector. (SCROLLBAR_VEC_SIZE, XSCROLLBAR, SCROLLBAR_PACK, SCROLLBAR_UNPACK, SCROLLBAR_X_WINDOW, SET_SCROLLBAR_X_WINDOW, VERTICAL_SCROLLBAR_INSIDE_WIDTH, VERTICAL_SCROLLBAR_TOP_RANGE, VERTICAL_SCROLLBAR_INSIDE_HEIGHT, VERTICAL_SCROLLBAR_MIN_HANDLE): New macros, to help deal with the lispy structures, and deal with the graphics. * frame.h (WINDOW_VERTICAL_SCROLLBAR): Macro deleted. (struct frame): New fields `scrollbars' and `condemned_scrollbars', for use by the scrollbar implementation. [MULTI_FRAME and not MULTI_FRAME] (FRAME_SCROLLBARS, FRAME_CONDEMNED_SCROLLBARS): Accessors for the new field. * window.h (struct window): Doc fix for vertical_scrollbar field. * frame.c (make_frame): Initialize the `scrollbars' and `condemned_scrollbars' fields of the new frame. * alloc.c (mark_object): Mark the `scrollbars' and `condemned_scrollbars' slots of frames. * xterm.c (x_window_to_scrollbar): Scrollbars are chained on frames' scrollbar field, not their x.display->vertical_scrollbars field. (x_scrollbar_create, x_scrollbar_set_handle, x_scrollbar_move, x_scrollbar_remove, XTset_vertical_scrollbar, XTcondemn_scrollbars, XTredeem_scrollbar, XTjudge_scrollbars, x_scrollbar_expose, x_scrollbar_handle_click, x_scrollbar_handle_motion): Substantially rewritten to correct typos and brainos, and to accomodate the lispy structures.
