From: Grazvydas Ignotas <nota...@gmail.com>
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.
