intel/isl: Refactor and clerify gen8 alignment calculations

Adding the actual table from the docs makes it clearer exactly what the
restrictions are.  In particular, it becomes clear that compressed
textures ignore the alignment parameters in RENDER_SURFACE_STATE.

drirc: Set glsl_zero_init for Kerbal Space Program.

This fixes the stripes of garbage rendered on the floor of the vehicle
assembly building among other rendering issues.  The reason for the
misrendering seems to be that some of the GLSL shaders used by the
application use variables before initializing them, incorrectly
assuming that they will be implicitly set to zero by the
implementation.

intel: tools: add aubinator_error_decode tool

This is pretty much the same tool as what i-g-t has, only with a more
fancy decoding of the instructions/registers. It also doesn't support
anything before gen4.

v2 (from Matt): Drop authors
                Remove undefined automake variable

v3: Fix incorrect offsets for dword > 1 (Jordan)

v4: Fix decompression error with large blobs (Jordan)

r600g: check rasterizer primitive states like in radeonsi

Specifically, non-line primitives skipped, and defaulting to reset on
each packet.

The skip of non-line primitives saves ≈110 resetting of
PA_SC_LINE_STIPPLE register per frame in Kane&Lynch2.

Note: si_shader.h has also "type" variable that should be changed to
"enum pipe_prim_type", however it triggers a bunch of warnings about
unhandled switches, so due not knowing the correct way to handle them, I
decided to leave it as is.
