Improve make-frame-on-display initial values

* doc/emacs/frames.texi (Multiple Displays): Add index entry for
'display server'.
* lisp/frame.el (make-frame-on-display): Specify sensible initial
values when reading display name.
* lisp/menu-bar.el (menu-bar-file-menu): Use 'display server' rather
than 'display' to avoid monitor<->display confusion.
