xenHypervisorNodeGetCellsFreeMemory was calling xend to find the number of cells on a node and keeping the information thereafter in a static variable. This patch just move the lookup code in the xen_unified driver, using the unified call (and hence the hypervisor instead of xend rpc). Provides the same for CPUs. Also helps centralizing those lookup in case Xen supports dynamic CPUs or cells in the future.
