util: import cache.c/h from glsl
It's not dependent on GLSL and it can be useful for shader caches that don't deal with GLSL. v2: address review comments v3: keep the other 3 lines in configure.ac Reviewed-by: Emil Velikov <[email protected]>

- * This cache provides two distinct operations:

- * o Storage and retrieval of arbitrary objects by cryptographic
- * name (or "key"). This is provided via cache_put() and
- * cache_get().
- *
- * o The ability to store a key alone and check later whether the

- *
- * The put_key()/has_key() operations are conceptually identical to
- * put()/get() with no data, but are provided separately to allow for
- * a more efficient implementation.
- *
- * In all cases, the keys are sequences of 20 bytes. It is anticipated
