This is partly copied+pasted from ANV but is mostly new code with lots
of reference counting bugs fixed (I hope!). The new cache caches
"object" which derive from a base vk_pipeline_class_object struct. It
uses a kernel-style "ops" interface for virtual methods on these objects
to allow for easy destruction (when the reference count hits zero) as
well as serialization an deserialization interfaces. This should allow
drivers to cache basically whatever they want without having to think
too hard about the details.
