datapath-windows: Hot add CPU support.
Hot add CPU is the ability to dynamically add CPUs to a running
system. Adding CPUs can occur physically by adding new hardware,
logically by online hardware partitioning, or virtually through
a virtualization layer.
This patch add support to reallocate any per-cpu resources, in
case a new processor is added.
