needed for mesa!4264

Also make it python2 and python3 compatible

We would like to switch to a drm-shim stub much like they other
drivers [1]. Therefore we won't need any stubbing code in this
repository.

You should run shader_db like this (for TGL platform) :

   intel_stub_gpu -p tgl ./run shaders/chromeos/

In addition to removing duplicate shaders from each application, shaders
that were the same across applications were removed.  All of the shaders
from the Wavelet Contour test were the same as the shaders from the Many
Spheres test.

I also removed trivial shaders.  Each test had several shaders where the
vertex shader was just 'gl_Position = mvp * gl_Vertex' and a fragment
shader that copied inputs to outputs (possibly with a conditional
discard).  These kinds of shaders are already well represented in
shader-db, IMHO.

Mesa handles the validation and translation into the right PCI IDs for
us, so just set INTEL_DEVID_OVERRIDE.

spill/fill changes are often the cause of large changes in
instruction and cycle count changes, so printing it on the same line (in
addition to the spill/fill section later) makes comprehending the
results easier.

On Fedora 31, libc.so no longer has symbols for fstat or fstat64.
I was not able to determine when this change occurred by
inspecting the history of glibc or glibc.spec, but they're gone
now. If dlsym() returns NULL for fstat{,64}, use __fxstat{,64} as
appropriate.

Add shaders extracted from skia's unit tests[1]

[1] https://skia.org/dev/testing/testing

Makes it much easier to see *which* shader hits a crash/etc when
debugging, as it ends up in nir->info.label.

These shaders are from chromeos start up - login screen to user session.

This commit adds a FOSSILIZE_BUILD_PATH variable which is a bit more
user-friendly than setting VK_LAYER_PATH manually because it's not as
obvious as one would like how to use that environment variable.  It also
appends $(basename $0) to the dump path so we get a nicely named .foz
file.  Finally, we stop adding unneeded directories.

We're currently only considering one shader per foz file because we
stick stuff in the hash based on the name for which we were only using
the name of the .foz file which meant we only considered a single shader
and it wasn't even guaranteed to be the same shader from both files.
To fix these issues, we instead use .foz/hash/ExecutableName as the name
so we get a complete name for the shader.  This should also let us more
easily identify the shaders in the output.

This script is pretty basic right now, it just counts the number of
cycles, etc and prints the diffs and the helped/hurt.

This has been designed to be generic, but we'll have to add additional
members for values other than the ones I've added.

Using the same default PCI-ID for TGL chosen by Mesa in
src/intel/dev/gen_device_info.c.

glmark2 is a popular OpenGL (2.1 / ES 2.0) benchmark on Linux. Let's add
its shaders. The shaders are licensed under the GPLv3
(https://github.com/glmark2/glmark2/blob/master/COPYING)

v2: Update COPYING to include GPL notice

Note: the shaders themselves don't have copyright notice, so the authors
are from grepping the main source tree:

	$ grep -hr Copyright *.cpp *.h | sort -h | uniq

I'm assuming nobody wrote shaders without touching the main tree.
