Add Xtrans definitions (FONT_t, TRANS_CLIENT) to clean up warnings. Add XSERV_t, TRANS_SERVER, TRANS_REOPEN to quash warnings. Add #include <dix-config.h> or <xorg-config.h>, as appropriate, to all source files in the xserver/xorg tree, predicated on defines of HAVE_{DIX,XORG}_CONFIG_H. Change all Xfont includes to <X11/fonts/foo.h>.

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.

Bug #14692: Allow drivers to have a say in Xinerama visual consolidation. Create a new exported global variable, XineramaVisualsEqualPtr. Use this pointer to decide whether two visuals are equal during visual consolidation. This pointer can be wrapped, which allows drivers and extensions to control which visuals are consolidated. A wrapper can reject the visuals without calling down, but must call down and return that result if it deems the visuals equal. This ensures that all layers agree that the visuals are equal. Pass the screen of the other visual into the VisualsEqual callchain. Don't free PanoramiXVisuals since we need it for PanoramiXTranslateVisualID. Don't skip the first visual on the other screen in PanoramiXMaybeAddVisual. Skip the loop in PanoramiXTranslateVisualID if screen is 0.
