ofproto: Add "ofproto/trace" command to help debugging flow tables.
With an appropriate flow table, output from a command like this:
ovs-appctl ofproto/trace system@dp0 0 0 ffffffffffff000c29f49d5c080600010
80006040001000c29f49d5cac10008a000000000000ac1004df00000000000000000000000000000
0000000
resembles the following:
