Add support for igmp and multicast

Multicast can be enabled through configuration or through command line
- Through configuration
  Add multicast=mcast_address (e.g. multicast=01:00:5e:01:02:03) in the port
  section
- Through command line
  run enable multicast port_id mcast_address (e.g. enable multicast 1 01:00:5e:01:02:03)

IGMP join message is sent unsollicited through command line:
  join igmp core_id task_id ip (e.g. join igmp 1 0 224.1.1.3)

To enable swap answering IGMP Query (w/ IGMP Join)
- Through configuration
  Add igmp ipv4=ip_address within the core/task section
- Through command line
  join igmp core_id task_id ip (e.g. join igmp 1 0 224.1.1.3)
  (this will 1st initiate an unsollicated join, then answer any subsequent query)

UDP/TCP packets received on a multicast address (224.0.0.0 => 239.255.255.255) are discarded

To stop sending responses to IGMP query:
  leave igmp core_id task_id

+;; This example uses 2 physical ports, connected back to back or through a
+;; switch.
+;; The 1st physical port (DPDK port 0) generates (through tasks 2 and 3 on
+;; core 1) 2x IGMP membership query per second: one towards 224.0.0.3 and
+;; one towards 224.0.0.4.
+;; mcast packets can be generated using "speed 1 0 1" (to generate packets
+;; on core 1, task 0 at 100Mbps) and "speed 1 1 1" (to generate packets
+;; on core 1, task 1 at 100Mbps). They will resp. generate mcast packets
+;; towards 224.0.0.3 and 224.0.0.4;
+
+;; 2x VF are configured on the second physical port.
+;; They receive packets from the generator, each on their own mcast address.
