This provides for using the existing DDX with future DRI drivers which
may break from the traditional names - but only with the help of the
user/packager. This scheme needs to be replaced with a robust mechanism
for driver loading if AIGLX and co are to be kept.

The automatic selection may not correspond with the correct backlight
(such as in a multi-gpu, multi-panel device) or the user may simply
prefer another control interface. This allows them to override the
chosen interface using
Option "Backlight" "my-backlight"
to specify '/sys/class/backlight/my-backlight' as the interface to use
instead.

Run the risk of a GPU hang (it shouldn't endanger the entire machine
normally) and let the user elect to disable it through
Option "NoAccel" "true"

As we've chosen to fix the kernel to handle CRTC offsets > 4096, drop
the automatic workaround. However, allow the user to force creation of
PerCrtcPixmaps for the purpose of debugging (and to workaround the bug
in older kernels) and to fallback to trying a shadow fb if the setcrtc
fails with the composite fb.

With the introduction of the third pipe on IvyBridge it is possible to
encounter situations where the combination of the three monitors exceed
the limits of the scanout engine and so prevent them being used at their
native resolutions. (It is conceivable to hit similar issues on earlier
generation, especially gen2/3.) One workaround, this patch, is to extend
the RandR shadow support to break the extended framebuffer into per-crtc
pixmaps.

Commit 8a9a585341 ("Only create a single instance of the intel_options
array") moved the definition of intel_options into a separate .c file.
Several of the defined options are #ifdef'd based on the configuration,
but since config.h is never included, the macros being tested are never
defined. Therefore, none of the configuration-specific options will
ever be available at runtime, even if they should be.
Add an inclusion of config.h so that such configuration-specific options
work again.
