Revert "mesa: Remove pointless comparison of unsigned integer with a negative constant."

This reverts commit a05fdbcb719ac64e6be842372813f0f4ca2f4f93.

Removing the comparison is wrong. The comparison with -1 should be changed
to another value (probably PROGRAM_UNDEFINED) along with another
change in the shader assembler.

intel: Remove non-kernel-exec-fencing support.

Shaves 60k off the driver from removing the broken spans code.  This
means we now require 2.6.29, which seems fair given that it's a year
old and we've removed support for non-KMS already in the last release
of 2D.

intel: Remove the unused s8 spans code.  Not hit during no_rast piglit.

Shaves 5.5k off of the driver.

softpipe: minor tweaks to texture filtering code

gallivm: implement texture border color, plus tweaks to some wrap modes

The progs/test/texwrap demo looks pretty good, but there are still some
tiny differences from softpipe.  There may be a sub-pixel texcoord
interpolation error somewhere.

There's some room for optimization.  Many of the wrap modes compute
intermediate values that are constant for the texture size (see the
min/max values).  These could be computed earlier and stored somewhere
for later use.

gallivm: added texture border_color field

xdemos: add OML sync test

Add program to test glXSwapBuffersMscOML behavior.  Based on glsync.c.

r300g: Fix indexbuf upper limits.

Wine tends to pessimistically use ~0 for its max index, but r300s
only can go up to 2^24-1, causing the kernel checker to freak out.

Civ4 is marginally improved now. Still crashes, but not as bad.

gallivm: rework and implement more texture wrap modes

All the texture wrap modes are now implemented for linear and nearest
sampling.

However, texture border color is not yet supported so some wrap modes
will produce int coords outside the texture bounds.  We'll get garbage
values insted of the texture border color for now.

gallivm: added lp_build_fract()

gallivm: added lp_build_set_sign()

gallivm: added lp_build_negate()

gallivm: clarify unsigned vs. signed integer type construction

The lp_int_type() function was creating an unsigned type.  So rename
that function to lp_uint_type() and create new lp_int_type() that
creates a signed type.

i915: Enable texture tiling by default.

This now passes piglit testcases, and shows performance improvements
on openarena.  Blit-heavy apps may see degradation, but the
expectation is that the common case of 3D rendering will see
significant wins.

This regresses gen-teximage on my 855, and no piglit tests on my 945.

i915: Fix up i830 for tiled drawing offsets.

Corresponds to b87406e55f029d29594ae76a4b39a4fe1007fe4f.
