ofproto-dpif: Implement translation of select groups.
		
Select bucket from those that are alive based on a hash of the destination
ethernet address of the packet.

Support for weights is proposed by a subsequent patch.

The selection is based on a hash of the destination ethernet
address of the flow. It should be possible to extend
this to cover a hash of user-specified elements of the flow.
