Denis Ovsienko 88d16c2dc6 OpenFlow 1.0: improve BSN extensions support 
Improve decoding of BSN vendor commands: update printing of commands
that set/get mirror port reporting flag, add decoding of shell exec
commands. Introduce decoding of vendor-specific actions with BSN as the
first such vendor and "mirror" as the first such BSN action.

Add a new test case based on a packet capture produced using Trema
controller and an Arista 7050SX-64 switch in Arista Networks' test lab.
Besides the structures above the capture contains the following items:

* OFPT_QUEUE_GET_CONFIG_REPLY with 0 queues (a valid edge case)
* OFPT_FEATURES_REPLY with ports 21 and 23 having bogus "config" field
  (a violation of the protocol, which required temporary patching of the
  controller to avoid the session shutdown)
* a set of IP mask manipulation BSN-specific commands
