The tiling setup needs a bit of work, but this should be good enough for now,
when we get buffers from the kernel we need to store their tiling properties.

draw llvm: fix storing of outputs for the rest of the pipeline
there's no good way of aligning the output's, and since the vertex_header
is variable sized in the first place we need to extract elements from a vector
and store them individually into an array. this gets the basic examples working
again
gallium: fix dri_destroy_option_cache() when optionCache.info is NULL
With an Intel 855GM handled by intel_drv, there's a crash with Gallium3D
enabled DRI driver for Intel i915 (--enable-gallium-intel).
The Gallium3D driver doesn't support the 855GM as expected by
intel_drv, it failed to open the screen and give an half
initialized screen structure to dri_destroy_option_cache():
optionCache.info is NULL, so it's crashing while trying
to free array content. This patch at least fix the crash in the function.
Here's some logs of the fixed version:

MAXWIDTH/HEIGHT were 2048 but the max texture size was 4096.
This caused a crash if a 4Kx4K texture was created and rendered to.
See comment about max framebuffer size in lp_scene.h.
Also added assertions to catch this inconsistancy in the future.
Putting calls to util_format_init all over the codebase is infeasible.
Instead, half float tables are pregenerated, and the s3tc library is
loaded on demand.
I believe this is a solution that combines performance, cleanliness,
flexibility and portability.
This changes the S3TC function pointers to be initialized to stubs
that load the S3TC library and then delegate to the real functions.
If the S3TC library fails to load, the function pointers are replaced
with a "nop" function.
The code is also changed to attempt to load the library only one time.c
Note that unlike checking for a flag, this method has no performance
cost at all.
The use of the "nop" functions also allows to avoid most checks, that
are only preserved when the function does non-trivial work.
This solution avoids the issue of how to run the initializers and
also allows those pages (and the parts of them in processor caches)
to be shared between multiple processes.
The drawback is slightly higher library size.
gallium/util: add util_format_init that inits s3tc and util_half
Switch from auto-init to explicit init for util_half per Brian Paul's
indication.
NOTE: this is probably broken because not enough things call util_format_init.
Will be fixed shortly
GLX/DRI2: pass GLX drawable ID to dri2InvalidateBuffers
The IDs will be the same in the case where an X window is used directly
as a GLX drawable, but will fail if a new GLX drawable is created
explicitly, as with glxgears_fbconfig.
Fixes fdo bug #27190.
