VIDEO: Allow more than one window.

Browse Source 
New sim_video APIs have been added to make it possible for a simulator
to open multiple windows.  Two slightly updated functions are:

t_stat vid_open_window (VID_DISPLAY **vptr, DEVICE *dptr, const char *title, uint32 width, uint32 height, int flags);

Like vid_open, but return a dynamically allocated VID_DISPLAY struct
and return it in *vptr.

t_stat vid_close_all (void);

Close all currently opened windows.

In addition, these new functions correspond completely to the old set
of sim_video functions, except the first argument is a VID_DISPLAY
pointer: vid_close_window, vid_map_rgb_window, vid_draw_window,
vid_refresh_window, vid_set_cursor_window, vid_show_video_window,
vid_is_fullscreen_window, vid_set_fullscreen_window,
vid_set_cursor_position_window.
