mesa 17.1.4

[Pierre Labastie]

New point version:

Mesa 17.1.4 is now available.

In this release we have:

In Mesa Core we include some fixes that involve flushing vertices
before some state changes.

The state tracker also received a fix for the Scissor with multiple
viewports.

The SPIR-V compiler has gotten a work around to prevent a shader bug in
Doom.

i965 has gotten many patches, including a couple of fixes for having
proper color interpolation in gen3, a bunch of corrections to avoid
hangings on Haswell, specially with fast-clear operations that happen
at the start of a batch, an initialization of the step rate for
interleaved vertex buffers to avoid rendering errors, a correction to
set the depth offset when there is only stencil attachment, a fix for
incorrect renderings due to using anisotropic filtering in nearest
mode, a fix for gl_Fragcoord's interpolation, a fix for Broxton 2x6 l3
config, a correction in Sky Lake for getting in-range clear colors, and
an improvement in gen7+ has been added to comply with OpenGL 4.1+.

anv has gotten a fix for L3 cache programming on Bay Trail.

Gallivm has seen a fix to avoid a segfault when we get invalid
glDrawRangeElements, a recursion that might have impacted performance
has been broken and, in the VA library, another fix has been added to
avoid memory corruptions.

The etnaviv driver has gotten a handful of patches, including fixes for
some resource copy issues, to prevent some fallout from the RB swapped
rendertarget work, to correct the max LOD bias, and a performance
regression has also been fixed.

The AMD drivers have received a fix for the proper generation of the
sid tables. radeonsi has gotten several improvements, including a new
polaris12 pci id and a deadlock fix while r600 is receiving a fix to
upload PBO textures to compressed textures.

The svga driver has received some patches to invalidate surfaces
correctly and a fix to properly unbind the GS.

nouveau's codegen has seen some improvements, including a fix to
properly fold constants in SPLIT operation.

EGL has gotten a couple of fixes to make the platform detection thread-
safe. The DRI2 drivers include now a fix to properly count configs. In
the case of the Android driver, we also got a workaround for apps which
choose their EGLConfig incorrectly and, in the case of the X11 one, a
crash fix has also been included.

From build and integration point of view, we have added a fix to solve
a linking problem for systems that lack libpthread.so, we have fixed a
recent build problem with Android and we have included also a missing
header for EGL, GLES and VG headers that was not included when EGL
building was disabled.
