This patch adds RubyPrefetcherProxy, which provides means to inject requests generated by the "classic" prefetchers into a SLICC prefetch queue. It defines defines notifyPf* functions to be used by protocols to notify a prefetcher. It also includes the probes required to interface with the classic implementation. AbstractController defines the accessor needed to snoop the caches. A followup patch will add support for RubyPrefetcherProxy in the CHI protocol.
