lisp/cus-face.el (custom-declare-face): Handle multiple concurrent display methods correctly. lisp/faces.el (x-create-frame-with-faces): Set the window-system frame parameter instead of frame-creation-function. (tty-create-frame-with-faces): Ditto. lisp/frame.el (frame-creation-function): Removed. (frame-creation-function-alist): New variable. (frame-initialize): Use initial-window-system instead of window-system. Add window-system parameter to initial-frame-alist. Removed tty initialization, it was moved to frame-creation-function-alist. (frame-notice-user-settings): Use initial-window-system instead of window-system. (make-frame-on-display): Make sure term/x-win is loaded. Added window-system parameter for make-frame. (make-frame-on-tty): Removed unnecessary autoload declaration. Added window-system parameter for make-frame. (make-frame): Use frame-creation-function-alist to determine the function to use depending on the specified window system. (select-frame-by-name): Use the window-system function instead of the variable. lisp/startup.el (window-system): New variable (previously built-in, now frame-local). (normal-top-level, command-line): Use initial-window-system instead of window-system. lisp/loadup.el: Load startup.el before faces.el, for the window-system variable. lisp/term/x-win.el: Check for the x-create-frame function instead of window-system to see if X is available. Don't exit Emacs if the display can not be opened when X is not the initial display method. Set up frame-creation-function-alist instead of frame-creation-function. Provide the x-win feature. src/dispnew.c (Vwindow_system): Renamed to Vinitial_window_system. (init_display, syms_of_display): Updated to use Vinitial_window_system instead of Vwindow_system. src/emacs.c (shut_down_emacs): Updated to use Vinitial_window_system instead of Vwindow_system. src/keyboard.c (Fset_input_mode): Call reset_all_sys_modes, not reset_sys_modes. Ditto for init_all_sys_modes. Process the quit parameter correctly. src/sysdep.c (init_sys_modes, reset_sys_modes): Unconditionally set up the terminal. We don't get called if there is nothing to do anymore. (sys_select): Use Vinitial_window_system, not Vwindow_system. src/window.h (Vwindow_system): Renamed to Vinitial_window_system. src/xfns.c (Fx_create_frame): Don't check_x. We initialize it anyway. (x_display_info_for_name, Fx_open_connection): Don't look at Vinitial_window_system. git-archimport-id: lorentey@elte.hu--2004/emacs--multi-tty--0--patch-54
