Change `keyboard-translate-table' to be terminal-local.

* lisp/subr.el (keyboard-translate): Use `terminal-local-value' to access `keyboard-translate-table'.
* lisp/obsolete/keyswap.el: Ditto.

* src/keyboard.c (Vkeyboard_translate_table): Moved to struct kboard.
* src/keyboard.h (Vkeyboard_translate_table): Moved to struct kboard.

* src/keyboard.c (read_char): Use current_kboard to access Vkeyboard_translate_table.
* src/keymap.c (Fdescribe_buffer_bindings): Ditto.

* src/keyboard.c (init_kboard): Initialize Vkeyboard_translate_table.

* src/keyboard.c (syms_of_keyboard): Use DEFVAR_KBOARD to define
  Vkeyboard_translate_table. Update doc strings.
