ruby: add a three level MESI protocol.
The first two levels (L0, L1) are private to the core, the third level (L2)is possibly shared. The protocol supports clustered designs. For example, one can have two sets of two cores. Each core has an L0 and L1 cache. There are two L2 controllers where each set accesses only one of the L2 controllers.
