Implement OpenFlow 1.5 port desc stats request.

Browse Source 
OpenFlow 1.4 and earlier always send the description of every port in
response to an OFPMP_PORT_DESC request.  OpenFlow 1.5 proposes allowing
the controller to request a description of a single port.  This commit
implements a prototype.
