e40cc5305b xselinux: Don't throw BadAccess if DixUnknownAccess is passed in to a hook. 
The avc will still appear, however, so that the callsite can be fixed.

ee21aba6be Fix Xinerama's consolidated visual handling. 
Formerly the code claimed it could only handle up to 256 visuals, which
was true.  Also true, but not explicitly stated, was that it could only
handle visuals with VID < 256.  If you have enough screens, and subsystems
that add lots of visuals, you can easily run off the end.  (Made worse
because we allocate visual IDs from the same pool as XIDs.)  If your app
then chooses a visual > 256, then the Xinerama code would throw BadMatch
on CreateColormap and your app wouldn't start.

With this change, PanoramiXVisualTable is gone.  Other subsystems that
were using it as a translation table between each screen's visuals now
use a PanoramiXTranslateVisual() helper.

f343265a28 XACE: Make the default window background state configurable per-window. 
To recap: the original XC-SECURITY extension disallowed background "None" if
the window was untrusted.  XACE 1.0 preserved this check as a hook function.
XACE pre-2.0 removed the hook and first abolished background "None entirely,
then restored it as a global on/off switch in response to Bug #13683.
Now it's back to being per-window, via a flag instead of a hook function.

97c82ce051 XACE: Restore the old background None behavior in response to bug #13683. 
From the X11 protocol spec:

"If background None is specified, the window has no defined background."

This means that toolkits and apps cannot rely on the "transparent" nature
of the current implementation!  At some point before the next release,
XACE will switch back to a solid background as the default.

d7c5e8bfc1 Modified performance patches from Arjan van de Ven <arjan@infradead.org> 
Subject: [PATCH] fix some performance gaps in Xace

The XaceHook function is used in several hotpaths.
The problem with it (performance wise) is twofold:
 * The XaceHook function has a big switch() statement for the hook number in it
 * The XaceHook function uses varargs to reassemble the final dispatch arguments again

Both are expensive operations... for something that is known at compile time

This patch turns the hotpath XaceHook call into a direct call to avoid
the switch and varargs; this gives me over 10% performance gain
on the x11perf benchmark.
