Instead of breaking the former when the driver supports the latter,
hook them up so that the hardware LUTs reflect the combination of the
current colourmap and gamma states. I.e. combine the colourmap, the
global gamma value/ramp and the RandR 1.2 per-CRTC gamma ramps into one
combined LUT per CRTC.
Fixes e.g. gamma sliders not working in games.

v2:
* Initialize palette_size and palette struct members, fixes crash on
server startup.
v3:
* Free randrp->palette in xf86RandR12CloseScreen, fixes memory leak.
v4:
* Call CMapUnwrapScreen if xf86RandR12InitGamma fails (Emil Velikov).
* Still allow xf86HandleColormaps to be called with a NULL loadPalette
parameter in the xf86_crtc_supports_gamma case.
v5:
* Clean up inner loops in xf86RandR12CrtcComputeGamma (Keith Packard)
* Move palette update out of per-CRTC loop in xf86RandR12LoadPalette
(Keith Packard)
v6:
* Handle reallocarray failure in xf86RandR12LoadPalette (Keith Packard)

This is strictly the application of the script 'x-indent-all.sh'
from util/modular. Compared to the patch that Daniel posted in
January, I've added a few indent flags:
-bap
-psl
-T PrivatePtr
-T pmWait
-T _XFUNCPROTOBEGIN
-T _XFUNCPROTOEND
-T _X_EXPORT
The typedefs were needed to make the output of sdksyms.sh match the
previous output, otherwise, the code is formatted badly enough that
sdksyms.sh generates incorrect output.
The generated code was compared with the previous version and found to
be essentially identical -- "assert" line numbers and BUILD_TIME were
the only differences found.
The comparison was done with this script:
dir1=$1
dir2=$2
for dir in $dir1 $dir2; do
(cd $dir && find . -name '*.o' | while read file; do
dir=`dirname $file`
base=`basename $file .o`
dump=$dir/$base.dump
objdump -d $file > $dump
done)
done
find $dir1 -name '*.dump' | while read dump; do
otherdump=`echo $dump | sed "s;$dir1;$dir2;"`
diff -u $dump $otherdump
done

When resetting the server, pScrn->EnterVT must be unwrapped or the
next server generation will end up wrapping the wrapper and causing an
infinite recursion on EnterVT.

Save in a few special cases, _X_EXPORT should not be used in C source
files. Instead, it should be used in headers, and the proper C source
include that header. Some special cases are symbols that need to be
shared between modules, but not expected to be used by external drivers,
and symbols that are accessible via LoaderSymbol/dlopen.
This patch also adds conditionally some new sdk header files, depending
on extensions enabled. These files were added to match pattern for
other extensions/modules, that is, have the headers "deciding" symbol
visibility in the sdk. These headers are:
o Xext/panoramiXsrv.h, Xext/panoramiX.h
o fbpict.h (unconditionally)
o vidmodeproc.h
o mioverlay.h (unconditionally, used only by xaa)
o xfixes.h (unconditionally, symbols required by dri2)
LoaderSymbol and similar functions now don't have different prototypes,
in loaderProcs.h and xf86Module.h, so that both headers can be included,
without the need of defining IN_LOADER.
xf86NewInputDevice() device prototype readded to xf86Xinput.h, but
not exported (and with a comment about it).
Add APIs to xf86RandR12 support and randr extension to record whether the
driver supports transforms, report that value in the RRGetCrtcTransform
reply.
xf86SetSingleMode tries to resize all crtcs to match the selected mode. When
a CRTC has no matching mode, it now disables the CRTC (instead of crashing).
Also, poke the RandR extension when xf86SetSingleMode is done so that
appropriate events can be delivered, and so that future RandR queries return
correct information.
(cherry picked from commit dc6c4f6989)
This code comes from the intel driver, so there's no history in this tree.
As the crtc/output-based mode selection code uses ddc, the ddc and i2c
modules have been merged into the server. Attempts to load them are safely
ignored now.
