Romain Francoise's and Ami Fischman's bugfixes.

Browse Source 
src/term.c (create_tty_output): Fix syntax error.  Reported by Ami
Fischman (ami at fischman dot org).

lisp/loadup.el: Load term/x-win.el if X is available.

lisp/startup.el (handle-args-function-alist)
(window-system-initialization-alist): New variables.
(command-line): Don't load term/x-win.el, use the above variables.

lisp/x-win.el: (x-initialize-window-system): New function, move X
initialization here.
(x-initialized): New variable.

lisp/frame.el (make-frame-on-display): Don't initialize X twice, and
make sure to pass the correct display parameter to x-open-connection.
Reported by Romain Francoise (romain at orebokech dot com).

THINGS TO DO
------------
** emacs -nw --eval '(y-or-n-p "Foobar")' segfaults.
** Fix color handling during tty+X combo sessions. (It seems that tty
sessions automatically convert the face colors to terminal colors
when the face is loaded. This conversion must happen instead on

;;; Commentary:
;; X-win.el: this file is loaded from ../lisp/startup.el when it recognizes
;; that X windows are to be used. Command line switches are parsed and those
;; pertaining to X are processed and removed from the command line. The
;; X display is opened and hooks are set for popping up the initial window.
;; X-win.el: this file defines functions to initialize the X window
;; system and process X-specific command line parameters before
;; creating the first X frame.
;; Note that contrary to previous Emacs versions, the act of loading
;; this file should not have the side effect of initializing the
;; window system or processing command line arguments (this file is
;; now loaded in loadup.el). See the variables
;; `handle-args-function-alist' and
;; `window-system-initialization-alist' for more details.
;; startup.el will then examine startup files, and eventually call the hooks
;; which create the first window(s).
