This reverts commit 9184af921bc2f332fcb6c9b47001414378eab8e2.
All X.Org modules must be able to be configured with autoconf 2.60.
In addition, version 2.63 has GPL licensing issues which prevents
some vendor to release software based on it.
The AM_SILENT_RULES are already handled by XORG_DEFAULT_OPTIONS.
All X.Org modules must be able to be configured with libtool 1.5.
AM_MAINTAINER_MODE default value is "enabled" already.
We use the same autogen script for all x.org modules.
There are proposals for changes which should be reviewed and eventually
applied to all modules together.
The lt*.m4 patterns are already included in the root .gitignore file.
This can be proposed as a change to all modules, but it invloves
changing the topvel .gitignore, the m4/.gitignore, the ACLOCAL_AMFLAGS
and the AC_CONFIG_MACRO_DIR together.
For more information on project wide configuration guidelines,
consult http://www.x.org/wiki/ModularDevelopersGuide
and http://www.x.org/wiki/NewModuleGuidelines.

The premise is that switching between rings (i.e. the BLT and
RENDER rings) on SandyBridge imposes a large latency overhead whilst
rendering. The cause is that in order to switch rings, we need to split
the batch earlier than is desired and to add serialisation between the
rings. Both of which incur large overhead.
By switching to using a pure 3D blit engine (ok, not so pure as the BLT
engine still has uses for the core drawing model which can not be easily
represented without a combinatorial explosion of shaders) we can take
advantage of additional efficiencies, such as relative relocations, that
have been incorporated into recent hardware advances. However, even
older hardware performs better from avoiding the implicit context
switches and from the batching efficiency of the 3D pipeline...
But this is X, and PolyGlyphBlt still exists and remains in use. So for
the operations that are not worth accelerating in hardware, we introduce a
shadow buffer mechanism through out and reintroduce pixmap migration.
Doing this efficiently is the cornerstone of ensuring that we do exploit
the increased potential of recent hardware for running old applications and
environments (i.e. so that the latest and greatest chip is actually faster
than gen2!)
For the curious, sna is SandyBridge's New Acceleration. If you are
running older chipsets and welcome the performance increase offered by
this patch, then you may choose to call it Snazzy instead.

gen3 ocitysmap 3494.05 (3502.44 0.20%) -> 4321.99 (4524.42 2.78%): 1.24x slowdown
gen4 ocitysmap 3628.42 (3641.66 9.37%) -> 5177.16 (5828.74 8.38%): 1.43x slowdown
gen5 ocitysmap 4027.77 (4068.11 0.80%) -> 5748.26 (6282.25 7.38%): 1.43x slowdown
gen6 ocitysmap 1401.61 (1402.24 0.40%) -> 2365.74 (2379.14 4.12%): 1.69x slowdown
[Note the performance regression for ocitysmap comes from that we now
attempt to support rendering to and (more importantly) from large
surfaces. By enabling such operations is the only way to one day be
faster than purely using the CPU, in the meantime we suffer regression
due to the increased migration and aperture thrashing. The other couple
of regressions will be eliminated with improved span and shader support,
now that the framework for such is in place.]
The performance increase for Cairo completely overlooks the other
critical aspects of the architecture:
World of Padman:
gen3 (800x600): 57.5 -> 96.2
gen4 (800x600): 47.8 -> 74.6
gen6 (1366x768): 100.4 -> 140.3 [F15]
144.3 -> 146.4 [drm-intel-next]
x11perf (gen6);
aa10text: 3.47 -> 14.3 Mglyphs/s [unthrottled!]
copywinwin10: 1.66 -> 1.99 Mops/s
copywinpix10: 2.28 -> 2.98 Mops/s
And we do not have a good measure for how much improvement the reworking
of the fallback paths give, except that xterm is now over 4x faster...
PS: This depends upon the Xorg patchset "Remove the cacheing of the last
scratch PixmapRec" for correct invalidations of scratch Pixmaps (used by
the dix to implement SHM operations, used by chromium and gtk+ pixbufs.

The git generated ChangeLog replaces the hand written one.
Update configure.ac to xorg-macros level 1.3.

This eliminates the cost of EXA migration management while providing full
