* progmodes/cc-vars.el (c-constant-symbol): New function which supersedes

c-const-symbol.  During a customize-.. call it enables an element of
(e.g.) c-hanging-braces alist to have its name displayed, even when the
default value of c-h-b etc. doesn't include the elemnt.  Replace uses of
the old function by the new.

* progmodes/cc-vars.el (c-hanging-braces-alist): Remove the obscure
non-working fragment ":value c-".
