In order to avoid costly fallback recompiles when cache items are
created with an old version of Mesa or for a different gpu on the
same system we want to create directories that look like this:
./{TIMESTAMP}_{LLVM_TIMESTAMP}/{GPU_ID}
Note: The disk cache util will take a single timestamp string, it is
up to the backend to concatenate the llvm string with the mesa string
if applicable.

Here we skip the recreation of uniform storage if we are relinking
after a cache miss. This is improtant because uniform values may
have already been set by the application and we don't want to reset
them.

This will allow us to skip certain things when falling back to
a full recompile on a cache miss such as avoiding reinitialising
uniforms.
In this change we use it to avoid reading the program metadata
from the cache and skipping linking during a fallback.

These may be lowered constant arrays or uniform values that we set before linking

The three additional tables are AttributeBindings, FragDataBindings,
and FragDataIndexBindings.
The first table (AttributeBindings) was identified as missing by
trying to test the shader cache with a program that called
glGetAttribLocation.
Many thanks to Tapani Pälli <tapani.palli@intel.com>, as it was review
of related work that he had done previously that pointed me to the
necessity to also save and restore FragDataBindings and
FragDataIndexBindings.

The scenario is:
glShaderSource
glCompileShader <-- deferred due to cache hit of shader
glShaderSource <-- with new source code
glAttachShader
glLinkProgram <-- no cache hit for program
At this point we need to compile the original source when we
fallback.

The hash key for glsl metadata is a hash of the hashes of each GLSL
source string.
This commit uses the put_key/get_key support in the cache put the SHA-1
hash of the source string for each successfully compiled shader into the
cache. This allows for early, optimistic returns from glCompileShader
(if the identical source string had been successfully compiled in the past),
in the hope that the final, linked shader will be found in the cache.
This is based on the intial patch by Carl.

This uses disk_cache.c to write out a serialization of various

compute.
This patch is based on the initial work done by Carl.

- add int64 support

From GLSL ES 3.10 spec, section 4.1.9 "Arrays":
"If an array is declared as the last member of a shader storage block
and the size is not specified at compile-time, it is sized at run-time.
In all other cases, arrays are sized only at compile-time."
In desktop GLSL it is allowed to have unsized-arrays that are
not last, as long as we can determine that they are implicitly
sized, which is detected at link-time.

the following shader:

Previously if you used MESA_GL_VERSION_OVERRIDE=3.3COMPAT, Mesa exposed
an OpenGL 3.3 compatibility profile context (with various unimplemented
features and bugs), but still refused to compile shaders with
#version 330 compatibility
This patch simply adds a small bit of plumbing to let that through.
Of course the same caveats apply: compatibility profile is still not
supported (and will not be supported), so there are no guarantees that
anything will work.
