Currently a gralloc internal structure is exposed to Mesa,
Use a query function instead to maintain ABI compatibility.

intel: Use a CPU map of the batch on LLC-sharing architectures.

Before, we were keeping a CPU-only buffer to accumulate the batchbuffer in,
which was an improvement over mapping the batch through the GTT directly
(since any readback or other failure to stream through write combining
correctly would hurt).  However, on LLC-sharing architectures we can do better
by mapping the batch directly, which reduces the cache footprint of the
application since we no longer have this extra copy of a batchbuffer around.

Improves performance of GLBenchmark 2.1 offscreen on IVB by 3.5% +/- 0.4%
(n=21).  Improves Lightsmark performance by 1.1 +/- 0.1% (n=76).  Improves
cairo-gl performance by 1.9% +/- 1.4% (n=57).

No statistically significant difference in GLB2.1 on SNB (n=37).  Improves
cairo-gl performance by 2.1% +/- 0.1% (n=278).
docs: List new extensions added in Mesa 9.1

I did not list the *_get_program_binary extensions since they're not
useful to anyone with their current implementation (that supports 0
binary formats).
Remove APIspec.dtd

intel: Un-hardcode lengths from blitter commands.

The packet length may change at some point in the future.  Specifying it
explicitly (rather than hardcoding it in the command #define) allows us
to change it much more easily in the future.

st/mesa: set ctx->Const.MaxSamples = 0, not 1

The gallium docs for pipe_screen::is_format_supported() says that
samples==0 or samples==1 both mean that multisampling is not supported.
Return GL_MAX_SAMPLES==0 instead of 1 for consistency with other drivers.

xlib: use _mesa_generate_mipmap() for mipmap generation, not meta

The swrast fragment program interpreter has trouble computing the
right texture LOD because it doesn't have easy access to input
derivatives.  This causes the GLSL-based meta generate mipmap code
to fetch texels from the wrong mipmap level.

One possible fix would be to set the GL_TEXTURE_MIN/MAX_LOD parameters
to limit sampling from the right level.  But let's just use the
_mesa_generate_mipmap() fallback since it's a lot faster than using
the fragment shader interpreter.

draw: fix draw_llvm_variant_key struct padding to avoid recompiles

The struct padding got broken by c789b981b244333cfc903bcd1e2fefc010500013.
This caused serious performance regression because part of the key was
uninitialized and hence the shader always recompiled (at least on release
builds...).
While here also fix key size calculation when the number of samplers
and the number of sampler views are different.
