This will be used to store more information about the cache item
in it's header. This information is intended for 3rd party and
cache analysis use but can also be used for detecting the unlikely
scenario of cache collisions.

Steam is already analysing cache items, unfortunatly we did not
introduce a versioning mechanism for identifying structural changes
to cache entries earlier so the only way to do so is to rename the
cache directory.
Since we are renaming it we take the opportunity to give the directory
a more meaningful name.
Adding a version field to the header of cache entries will help us to
avoid having to rename the directory in future. Please note this is
versioning for the internal structure of the entries as defined in
disk_cache.{c,h} as opposed to the structure of the data provided to
the disk cache by the GLSL compiler and the various driver backends.

This will be used for things such as adding driver specific environment
variables to the key. Allowing us to set environment vars that change
the shader and not have the driver ignore them if it finds existing
shaders in the cache.

This allows to get rid of the arch and gpu name directories.
v2: (Timothy Arceri) don't use an opaque data type to store
pointer size and gpu name.
v3: (Timothy Arceri) use blob to store driver keys just make sure
to store null terminator for strings, and make sure blob is
defined by disk_cache and not it's users.
v4: (Timothy Arceri) fix typo, and make ptr_size a uint8_t.

This will allow to hash additional data into the cache keys or even
change the hashing algorithm easily, should we decide to do so.

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.

This will be used to remove cache items created with old versions
of Mesa or other invalid cache items from the cache.
V2: rename stub function (cache_* funtions were renamed disk_cache_*)

Earlier commit imported a SHA1 implementation and relaxed the SHA1 and
disk cache handling, broking the Windows builds.
Restrict things for now until we get to a proper fix.
Fixes: d1efa09d34 "util: import sha1 implementation from OpenBSD"
Signed-off-by: Emil Velikov <emil.velikov@collabora.com>
At the moment we support 5+ different implementations each with varying
amount of bugs - from thread safely problems [1], to outright broken
implementation(s) [2]
In order to accommodate these we have 150+ lines of configure script and
extra two configure toggles. Whist an actual implementation being
~200loc and our current compat wrapping ~250.
Let's not forget that different people use different code paths, thus
effectively makes it harder to test and debug since the default
implementation is automatically detected.
To minimise all these lovely experiences, import the "100% Public
Domain" OpenBSD sha1 implementation. Clearly document any changes needed
to get building correctly, since many/most of those can be upstreamed
making future syncs easier.
As an added bonus this will avoid all the 'fun' experiences trying to
integrate it with the Android and SCons builds.
v2: Manually expand __BEGIN_DECLS/__END_DECLS and document (Tapani).
Furthermore it seems that some games (or surrounding runtime) static
link against OpenSSL resulting in conflicts. For more information see
