intel: Enable stripping of texture borders.
This replaces software rendering of textures with the deprecated
1-pixel border (which is always bad, since mipmapping is rather broken
in swrast, and GLSL 1.30 is unsupported) with hardware rendering that
just pretends there was never a border (so you have potential seams on
apps that actually intentionally used the 1-pixel borders, but correct
rendering otherwise).
This doesn't regress any piglit tests on gen6 (since the texwrap
border/bordercolor cases already failed due to broken border color
handling), but regresses texwrap border cases on original gen4 since
those end up sampling the border color instead of the border pixels.
It's a small price to pay for not thinking about texture borders any
more.

ralloc: Add new [v]asprintf_rewrite_tail functions.
This can be useful if you want to create a bunch of temporary strings
with a common prefix. For example, when iterating over uniform
structure fields, one might want to create temporary strings like
"pallete.primary", "palette.outline", and "pallette.shadow".
This could be done by overwriting the '.' with a null-byte and calling
ralloc_asprintf_append, but that incurs the cost of strlen("pallete")
every time...when this is already known.
These new functions allow you rewrite the tail of the string, given a
starting index. If the starting index is the length of the string, this
is equivalent to appending.

linker: Eliminate more dead code after demoting shader inputs and outputs
Consider the following vertex shader and fragment shader:
// vertex shader
varying vec4 v;
uniform vec4 u;
void main() { gl_Position = vec4(0.0); v = u; }
// fragment shader
void main() { gl_FragColor = vec4(0.0); }
Since the fragment shader does not use 'v', it is demoted from a
varying to a simple global variable. Once that happens, the
assignment to 'v' is useless, and it should be removed. In addition,
'u' is no longer active, and it should also be removed.
Performing extra dead code elimination after demoting shader inputs
and outputs takes care of this. This elimination must occur before
assigning uniform locations, or the declaration of 'u' cannot be
removed.
This change *breaks* the piglit test getuniform-01, but that test is
already incorrect. The test uses a vertex shader that assigns to a
user-defined varying, but it has no fragment shader. Since Mesa does
not support ARB_separate_shader_objects (we only support the EXT
version), the linker correctly eliminates the user-defined varying.
The cascading effect is that the uniform queried by the C code of the
test is also (correctly) eliminated.

i965: Remove "single threaded" INTEL_DEBUG mode.
According to the docs for 3DSTATE_PS (Gen7+) and 3DSTATE_WM (Gen6),
there is a platform dependent value for the minimum number of pixel
shader threads. It may also vary based on whether WIZ Hashing is on.
For example, Ivybridge requires at least 4 threads if WIZ hashing is
disabled, and 8 if it's enabled. Programming it to use less threads is
illegal. Sandybridge appears to have similar restrictions.
So on newer platforms, INTEL_DEBUG=sing will probably just hang the GPU.
Rather than try to patch it up for newer platforms and extend it to
support geometry shaders, just remove it as it isn't that useful anyway.
