This adds the various mesa->gallium and gallium->mesa format conversions
along with the GL->gallium texture choosers for integers.

This add support for unsigned/signed integer types via adding a 'pure' bit
in the format description table. It adds 4 new u_format get/put hooks,
for get/put uint and get/put sint so that accessors can get native access
to the integer bits. This is used to avoid precision loss via float converting
paths.
It doesn't add any float fetchers for these types at the moment, GL doesn't
require float fetching from these types and I expect we'll introduce a lot
of hidden bugs if we start allowing such conversions without an API mandating
it.
It adds all formats from EXT_texture_integer and EXT_texture_rg.
0 regressions on llvmpipe here with this.
(there is some more follow on code in my gallium-int-work branch, bringing
softpipe and mesa to a pretty integer clean state)
v2: fixup python generator to get signed->unsigned and unsigned->signed
fetches working.

This fixes up the integer format choosing to pick the closest mesa format
then the most likely fallback.
(the formatting in this file needs cleaning in another patch).

This just adds a simple packing for GL_UNSIGNED_INT/GL_INT destination formats.
This is enough for at least the gallium drivers to pack both unsigned and signed types for read pixels.

Most of these functions used three spaces for the first level of
indentation, but four spaces for the next level. One used tabs and then
three spaces. Some used 3/4 in a then block but 3/3 in the else block.
Normally I try to avoid field days like this, but since the functions
were so inconsistent, even internally, it was making it difficult to
edit without introducing spurious whitespace changes.
So, just get it over with. git diff -b shows 0 lines changed.

i915 and i830 hardware doesn't have HiZ, so remove all HiZ related
assertions from *update_draw_buffer().
I've removed the dead format checks completely rather than replace them
with more appropriate checks. This doesn't reduce "assertion coverage",
however, because when I added these HiZ related assertions in c8fdf66
there were no pre-existing checks there.

Silences a warning about comparing to an unsigned variable. It looks like
the result of swizzle_for_size() is always assigned to unsigned vars.

This fixes failures found with the new piglit texsubimage test.
Two things were broken:
1. The dxt code doesn't handle sources images where width != row stride.
Check for that and take the _mesa_make_temp_ubyte_image() path to get
an image where width = rowstride.
2. If we don't take the _mesa_make_temp_ubyte_image() path we need to
take the source image unpacking parameters into account in order to
get the proper starting memory address of the source texels.
Note: This is a candidate for the 7.11 branch.
Docs say that default shader input color input need to be spec
as ARGB8888. And a clear rect prim essentially uses this value
instead of default diffuse. Depth on the other hands is an ieee
32 bit float. Clear stencil is U8.
Completely different are the clear values for zone init prims.
These are speced in the actual output pixel layout (and need
to be repeated for 16 bit formats).
Clear up the confusion by adding some comments.
v2: Retain the target swizzling support added by Stephan Marchesin.

Previously, if the user enabled a non-consecutive set of clip planes
(e.g. 0, 1, and 3), the driver would compact them down to a
consecutive set starting at 0. This optimization was of dubious
value, and complicated the implementation of gl_ClipDistance.
This patch changes the driver so that with Gen6 and later chipsets, we
no longer compact the clip planes. However, we still discard any clip
planes beyond the highest number that is in use, so performance should
not be affected for applications that use clip planes consecutively
from 0.
With chipsets previous to Gen6, we still compact the clip planes,
since the pre-Gen6 clipper thread relies on this behavior.

The only remaining uses of brw_vs_prog_key::nr_userclip only occurred
when using clip planes (as opposed to gl_ClipDistance). This patch
renames the value to nr_userclip_planes and sets it to zero when
gl_ClipDistance is in use. This avoids unnecessary VS recompiles.
