Subject: Fix UTF-8 tty input when first frame is an X frame.  Steps towards
 multiple tty locale support.

* lisp/international/mule-cmds.el (set-locale-environment): Ignore
  window-system; always set the keyboard coding system.


* src/termhooks.h (DISPLAY_TERMINAL_CODING, DISPLAY_KEYBOARD_CODING): New macros.

* src/coding.c (Fset_terminal_coding_system_internal, Fterminal_coding_system)
  (Fset_keyboard_coding_system_internal, Fkeyboard_coding_system): Add DISPLAY
  parameter.

* src/term.c (get_display): Add THROW parameter.
  (get_tty_display, Fdisplay_name, Fdisplay_tty_type, Fdisplay_controlling_tty_p)
  (Fdelete_display, Fdisplay_live_p): Update callers.
* src/xfns.c (check_x_display_info): Ditto.
* src/frame.c (Fmake_terminal_frame, Fframe_display): Ditto.

* src/dispextern.h (get_display): Update prototype.

* lisp/international/mule.el (set-terminal-coding-system)
  (set-keyboard-coding-system): Add DISPLAY parameter.
