Bring back ElDoc's eldoc-display-message-p, but obsolete it

Like others, this is an implementation detail that third parties could
be relying on.  Better not remove it outright just now, since its
implementation is very simple anyway.

* lisp/emacs-lisp/eldoc.el (Version): Bump to 1.7.0
(eldoc-display-message-p): Bring back, but obsolete.
