bdf289e7fb i965: Fix crash when calling glViewport with no surface bound
If EGL_KHR_surfaceless_context is used then glViewport can be called
with NULL for the draw and read surfaces. This was previously causing
a crash because the i965 driver tries to use this point to invalidate
the surfaces and it was derferencing the NULL pointer.

ab0b96a939 vc4: Warn instead of abort()ing on exec ioctl failures.
It's really harsh to abort() the X Server because of a momentary failure
(particularly -ENOMEM).  I don't see a way to pass an -ENOMEM up the stack
from here, but we can at least log to stderr before proceeding on.

d4474a96df meta/generate_mipmap: Work-around GLES 1.x problem with GL_DRAW_FRAMEBUFFER
GL_DRAW_FRAMEBUFFER does not exist in OpenGL ES 1.x, and since
_mesa_meta_begin hasn't been called yet, we have to work-around API
difficulties.  The whole reason that GL_DRAW_FRAMEBUFFER is used instead
of GL_FRAMEBUFFER is that the read framebuffer may be different.  This
is moot in OpenGL ES 1.x.

I have another patch series that would also fix this (by removing the
calls to _mesa_BindFramebuffer and friends), but it's not quite ready
yet... and I think it may be a bit heavy for some stable branches.
Consider this a stop-gap fix.

66e0a26b56 glsl: assign varying locations to tess shaders when doing SSO
GRID Autosport uses SSO shaders. When a tessellation evaluation shader
is passed through this, it triggers assertion failures down the line
with unassigned varying locations. Make sure to do this when the first
shader in the pipeline is not a vertex shader.

a98bc49997 i965: Add B8G8R8X8_SRGB to the alpha format override
brw_init_surface_formats overrides the render format for RGBX formats
which aren't supported for rendering so that they internally use RGBA
instead. However, B8G8R8X8_SRGB was missing so it wasn't marked as a

55d9c80d21 gk104/ir: simplify and fool-proof texbar algorithm
With the current algorithm, we only look at tex uses. However there's a
write-after-write hazard where we might decide to, on some path, not use
a texture's output at all, but instead to write a different value to
that register. However without the barrier, the texture might complete
later and overwrite that value.

This fixes Unreal Elemental demo on GK110/GK208, flightgear on GK10x,
and likely other random-looking failures.

fce9699bca mesa/shader: return correct attribute location for double matrix arrays
If we have a dmat2[4], then dmat2[0] is at 17, dmat2[1] at 19,
dmat2[2] at 21 etc. The old code was returning 17,18,19.

I think this code is also wrong for float matricies as well.

There is now a piglit for the float case.

86100d4ca9 gallium/util: return correct number of bound vertex buffers
In case a state tracker unbinds every slot by a seperate
pipe->set_vertex_buffers() call, starting from slot zero, the number
of bound buffers would not reach zero at all.
The current algorithm does not account for pre-existing holes in the
buffer list.

Unbinding all buffers at once or starting at the top-most slot results
in correct behaviour.

Calculating the correct number of bound buffers fixes a NULL pointer
dereference in nvc0_validate_vertex_buffers_shared().

a16f5195ef glsl: don't generate extra errors in ValidateProgramPipeline
From Section 11.1.3.11 (Validation) of the GLES 3.1 spec:

   "An INVALID_OPERATION error is generated by any command that trans-
   fers vertices to the GL or launches compute work if the current set
   of active program objects cannot be executed, for reasons including:"

It then goes on to list the rules we validate in the
_mesa_validate_program_pipeline() function.

For ValidateProgramPipeline the only mention of generating an error is:

   "An INVALID_OPERATION error is generated if pipeline is not a name re-
   turned from a previous call to GenProgramPipelines or if such a name has
   since been deleted by DeleteProgramPipelines,"

Which we handle separately.

This fixes:
ES31-CTS.sepshaderobjs.PipelineApi

No regressions on the eEQP 3.1 tests.

aa19234943 glsl: don't sort varying in separate shader mode
This fixes an issue where the addition of the FLAT qualifier in
varying_matches::record() can break the expected varying order.

It also avoids a future issue with the relaxing of interpolation
qualifier matching constraints in GLSL 4.50.

66f216d8ce glsl: don't dead code remove SSO varyings marked as active
GL_ARB_separate_shader_objects allow matching by name variable or block
interface. Input varyings can't be removed because it is will impact the
location assignment.

This fixes the bug 79783 and likely any application that uses
GL_ARB_separate_shader_objects extension.
