    Cherry-pick a fix for selection for TouchBegin from multiple clients
    
    From IRC:
    
    14:07 <Jasper> ajax, airlied: can we backport
    http://cgit.freedesktop.org/xorg/xserver/commit/?id=314776eb369ca2e438907795ae030dd743c281fc
    to the Fedora X server? It's causing some issues for GTK+ clients.
    14:07 <ajax> i don't see why not

+Subject: [PATCH] Touch: Fix duplicate TouchBegin selection with virtual
+ devices
+
+Given the following scenario:
+  1) client A selects for TouchBegin on window W for device D
+  2) client B selects for TouchBegin on window W for XIAllDevices
+  3) client C selects for TouchBegin on window W with device E
+
+Step 3 will fail with BadImplementation, because attempting to look up
+XIAllDevices or XIAllMasterDevices with dixLookupDevices doesn't work.
+This should succeed (or, if it was selecting for device D, fail with
+BadAccess as it would be a duplicate selection).
+
+Fix this by performing the appropriate lookup for virtual devices.
