pv: new variable $rcv(key)

- available inside event_route[core:msg-received]
- get details of the received message - the key can be:
  * buf - received message
  * len - lenght of received message
  * srcip - source ip
  * rcvip - local ip where it was received
  * scrport - source port
  * rcvport - local port where it was received
  * proto - protocol as int id
  * sproto - protocol as string
  * af - address family
