Explicitly set the version that is implemented, as that may differ
from the one defined in dri_interface.h. Use designated initialisers
and constify whereever possible.
Note: __DRIimageExtension should not be made const as it's modified
at runtime. This patch should have no side effects on compilers that
do not support designated initialisers, as the existing code in
dri/common already uses them.

The old python code used sys.is_big_endian to select between little-endian
and big-endian formats, which meant that the build and host endiannesses
needed to be the same. This patch instead generates both big- and little-
endian layouts, using PIPE_ARCH_BIG_ENDIAN to select between them.

Rather than iterate over format.channels and format.swizzles directly,
use Python subfunctions that take the channel and swizzle lists as
arguments. This allow the channel and swizzle lists to depend on
endianness.

In all fairness we allow the gallium tests to be build with --disable-dri
which will result in the approapriate winsys to not be build, thus the
build will fail.

The function relies on the sw/dri winsys which is build only when --enable-dri
is set. Fixes build issues with the following config
./configure --disable-dri --with-gallium-drivers=svga --enable-xa
Issue can be reproduced with any hw gallium driver + st that uses the pipe-loader.

GL (3.0) allows you to clear individual color buffers in a fb. In fact
for fbs containing both int and float/normalized color buffers this is
required (because the clearing values are otherwise undefined if applied
to all buffers). The gallium interface was changed a while ago, but llvmpipe
ignored it (hence doing such individual clears always resulted in clearing
all buffers, plus some assorted asserts due to the mixed fbs).
So change the clear command to indicate the buffer to be cleared. Also, because
indicating the buffer to be cleared would have made lp_rast_arg_cmd larger
which is unacceptable (we're trying to shrink it some day) allocate the clear
value in the scene and just pass a pointer.
There's several advantages and disadvantages here:
+ clearing individual buffers works (we could also actually bin such clears now
if they'd come through clear_render_target() if the surface is in the current
fb, though we didn't do this before for the single rb case and still don't try).
+ since there's one clear per rb, we do the format conversion in setup rather
than per bin. Aside from the (drop in the ocean...) performance advantage this
means that clearing to very small values (that is, denormal when converted to
the format) should work for small float (fp16 etc.) formats, as the util code
couldn't handle it correctly before (because cpu denorms are disabled when
executing the bin commands, screwing up the magic conversion and flushing
the values to 0, though this was not verified).
- there's some overhead for traditional old-style clear-all MRT cases, since
there's one rast clear command per rb instead of one for all rbs.
This fixes https://bugs.freedesktop.org/show_bug.cgi?id=76976.
v2: get rid of the ugly manual memcpy stuff and just use union util_color.
This is 32 bytes instead of 16 but as the allocation is per scene we can live
with those additional 16 bytes (and the additional 128 bytes in the setup
context), which makes the code much more obvious. Suggested by Brian.

util_color often merely represents a collection of bytes, however it is
inconvenient if those bytes can only be accessed as floats/doubles for int
formats exceeding 32bits.
(Note that since rgba8 formats use one uint, not 4 bytes, hence the byte and
short member were left as is.)
Changing SX_MISC hangs RV740. When we're at it, let's use DX_RASTERIZATION_KILL
on all R700 and later chipsets.

The current version checking is wrongly refusing to create 3.3 contexts;
unsupported version are checked elsewhere; and the DRI path doesn't do
this sort of checking neither.

The GLX_ARB_create_context_profile spec says:
"If version 3.1 is requested, the context returned may implement
any of the following versions:
* Version 3.1. The GL_ARB_compatibility extension may or may not
be implemented, as determined by the implementation.
* The core profile of version 3.2 or greater."
Mesa does not support GL_ARB_compatibility, and there are no plans to
ever support it, therefore the only chance to honour a 3.1 context is
through core profile, i.e, the 2nd alternative from the spec.
This change does that. And with it piglit tests that require 3.1
contexts no longer skip.
Assuming there is no objection with this change, src/glx/dri_common.c
and src/gallium/state_trackers/wgl/stw_context.c should also be updated
accordingly, given they have the same logic.
