util/u_format_s3tc: handle srgb formats correctly.

Instead of just ignoring the srgb/linear conversions, simply call the
corresponding conversion functions, for all of pack/unpack/fetch,
both for float and unorm8 versions (though some don't make a whole
lot of sense, i.e. unorm8/unorm8 srgb/linear combinations).
Refactored some functions a bit so don't have to duplicate all the code
(there's a slight change for packing dxt1_rgb, as there will now be
always 4 components initialized and sent to the external compression
function so the same code can be used for all, the quite horrid and
ad-hoc interface (by now) should always have worked with that).

Fixes llvmpipe/softpipe piglit texwrap GL_EXT_texture_sRGB-s3tc.

gallivm: (trivial) simplify lp_build_cos/lp_build_sin a tiny bit

Use "or" instead of "add" (this is a classic select sequence, which at
least newer llvm versions can actually recognize (3.2+?), and the "add"
might prevent that - and we really don't want an add instead of an or with
avx if it isn't recognized (even without avx logic ops might be cheaper)).

nv50: H.264/MPEG2 decoding support via VP2, available on NV84-NV96, NVA0

Adds H.264 and MPEG2 codec support via VP2, using firmware from the
blob. Acceleration is supported at the bitstream level for H.264 and
IDCT level for MPEG2.

Known issues:
 - H.264 interlaced doesn't render properly
 - H.264 shows very occasional artifacts on a small fraction of videos
 - MPEG2 + VDPAU shows frequent but small artifacts, which aren't there
   when using XvMC on the same videos

llvmpipe: fix blending with SRC_ALPHA_SATURATE with some formats without alpha

We were fixing up the blend factor to ZERO, however this only works correctly
with fixed point render buffers where the input values are clamped to 0/1
(because src_alpha_saturate is min(As, 1-Ad) so can be negative with unclamped
inputs). Haven't seen any failure anywhere due to that with fixed point SNORM
buffers (which clamp inputs to -1/1) but it should apply there as well (snorm
blending is rare, even opengl 4.3 doesn't require snorm rendertargets at all,
d3d10 requires them but they are not blendable).
Doesn't look like piglit hits this though (some internal testing hits the
float case at least). (With legacy OpenGL we could theoretically still use the
fixup to zero if the fragment color clamp is enabled, but we can't detect that
easily since we don't support native clamping hence it gets baked into the
shader.)

llvmpipe: clamp inputs for srgb render buffers

Usually with fixed point renderbuffers clamping is done as part of conversion.
However, since we blend in float format, we essentially skip all conversion
steps pre-blend but since this is still a fixed point renderbuffer we must
still clamp the inputs in this case. Makes no difference for piglit though.
Obviously we could skip this if fragment color clamping is enabled, but a)
this is deprecated in OpenGL (d3d never had it) and b) we don't support it
natively so it gets baked into the shader.
Also add some comment about logic ops being broken for srgb, luckily no test
tries to do that as there's no easy fix...

builtin_compiler/build: Avoid using libtool if cross compiling

Adds the dependencies of builtin_compiler as sources when cross

The builtin_compiler executable is built for the host when cross
compiling so it doesn't make sense to share compilation with src/glsl

gen_matypes: fix cross-compiling with gcc

The current gen_matypes logic assumes that the host compiler will produce
information that is useful for the target compiler.  Unfortunately, this
is not the case whenever cross-compiling.

When we detect that we're cross-compiling and using GCC, use the target
compiler to produce assembly from the gen_matypes.c source, then process
it with a shell script to create a usable header.  This is similar to how
the linux kernel creates its asm-offsets.c file.
