(c-buffer-is-cc-mode): Definition moved here from cc-vars.el.

Also, put permanent-local property on variable so it's value won't get
killed by kill-all-local-variables.  This makes it easier for non-CC
Mode derived modes to be initialized correctly.

(c++-mode, java-mode, objc-mode, idl-mode):
Remove obsolete variable c-double-slash-is-comments-p.
