* lisp/electric.el (electric-indent-mode-has-been-called): Remove.

(electric-indent-mode): Fix accordingly.
* lisp/progmodes/cc-mode.el (c-initialize-cc-mode): Only hook into
electric-indent-mode-hook if we obey electric-indent-mode.
(c-basic-common-init): Use (fboundp 'electric-indent-local-mode) to
decide whether we obey electric-indent-mode.
(c-change-set-fl-decl-start, c-extend-after-change-region):
Silence warnings.
(c-electric-indent-mode-hook): Assume we do want to obey
electric-indent-mode.
