bug#25523: 25.1; rename `cl-caddr' etc. to `caddr' etc.

It is ridulous that these ever got renamed to cl-*.  Lisp deserves
more respect than that.

It is doubly ridiculous that the aliases for them, which remove the
silly `cl-' prefix, are in a _completely different library_.  So even if
you require `cl-lib.el' you do not get the aliases (the aliases are in
`cl.el').

It is hard to believe that anyone implemented this.  It is high time to
fix it.  (It's now been almost a year since that emacs-devel
discussion.)
