Subject: Fix semantics of terminal-local variables.  Remove
 `terminal-local-value' hack.

* src/data.c (do_symval_forwarding, store_symval_forwarding)
  (find_symbol_value): Use the selected frame's keyboard, not
  current_kboard.

* src/data.c (Fterminal_local_value, Fset_terminal_local_value): Disable
  these functions.

* src/data.c (syms_of_data): Don't defsubr them.
* lisp/edmacro.el (edmacro-format-keys): Remove terminal-local-value calls.
* lisp/emulation/cua-base.el (cua--pre-command-handler-1): Ditto.
* lisp/international/encoded-kb.el (encoded-kbd-setup-display): Ditto.

* lisp/simple.el (normal-erase-is-backspace-mode): Ditto.
* lisp/subr.el (keyboard-translate, read-quoted-char): Ditto.
* lisp/term/AT386.el (terminal-init-AT386): Ditto.
