Correct OF1.4 OFPMatch JSON serialisation and formatting

Prior to this patch the code serialises an OFPMatch as:

   "OFPMatch": {
      "oxm_fields": {
         "arp_op": 1,
         ...
      }
   }

But the parser fails, complaining that "oxm_fields" is an unknown field name.

Resolve this by using the same JSON format as OF1.3:

   "OFPMatch": {
      "length": 329,
      "oxm_fields": [
         {
            "OXMTlv": {
               "field": "in_port",
               "mask": null,
               "value": 84281096
            }
         },
         ...
      }
   }

Add OF1.4 OFPMatchField support

This covers fields that are also present in OF1.3.
In particular it does not cover PBB_UCA.
I plan to address this in a subsequent patch.
