Handle --version reasonably in CANNOT_DUMP configuration.

* src/emacs.c (emacs_version, emacs_copyright): New string variables. (Vemacs_version, Vemacs_copyright): New Lisp_Object variables. (syms_of_emacs): Defvar them, and initialize them from the C string variables. (main): If initialization hasn't been done, print initial version info from the C strings, instead of starting an interactive session. * lisp/version.el (emacs-copyright, emacs-version): Don't define here. * configure.in: Look for version string in its new place.
