Further simplify Xinerama init and re-init on XRR events.

While testing for Xinerama during setup was done display-wide, each time
XineramaQueryScreens() is called either in start-up or due to an XRR
event, the library re-tests for the Xinerama extension anyway before
moving on; so the initial test is redundant and allows another global to
go away with one other change: always fill in sc->xinerama (and _no),
regardless of the success of malloc in XineramaQueryScreens(), and use
it to see if Xinerama dimensions exist when asked by client and/or menu
code.

-This is a port of OpenBSD's excellent cwm[0] to Linux and other
-Unices.
-
-    cwm is a window manager for X11 which contains many features that
-    concentrate on the efficiency and transparency of window
-    management.  cwm also aims to maintain the simplest and most
-    pleasant aesthetic.
-
-This port requires pkg-config, Xft, Xinerama and Xrandr.  The included
-Makefile should work with both GNU make and BSD make.
-
-This version actively tracks changes in the OpenBSD CVS repository.
-Releases are roughly coordinated.
-
-The revision controlled version is at https://github.com/chneukirchen/cwm
-Releases can be found at http://chneukirchen.org/releases
-
-ChangeLog:
-
-2012-05-02: First public release 5.1 of portable cwm.
