Tiago Mück	3a7192d682	mem-cache: change hasBeenPrefetched ... hasBeenPrefetched can now take a requestor id and returns true only if the block was prefetched by a prefetcher with the same id. This may be necessary to properly train multiple prefetchers attached to the same cache. If returns true if the block was prefetched by any prefetcher when the id is not provided.

Tiago Mück	d8a04f902e	mem-cache: add prefetch info to update probe ... CacheDataUpdateProbeArg has additional info to tell listeners if the block was prefetched and evicted without being used, as well as which object prefetched the block.

Tiago Mück	af2ee0db30	mem-cache: decoupled prefetchers from cache ... This patches decouples the prefetchers from the cache implementation as the first step to allow using the classic prefetchers with ruby caches. The prefetchers that need do cache lookups can do so using the accessor object provided when the probes are notified. This may also facilitate connecting the same prefetcher to multiple caches.
