Added support for reporting packet (mis)order.

The "Latency" screen has been updated with 3 columns:
- mis-ordered
  Count the number of mis-ordered packets.
- extent:
  Gives an indication of how mis-ordered the packets are.
  Receiving packet "x - 5" after receiving packet "x" will
  cause an extent of 5.
- duplicate:
  Count number of duplicate packets.

Following commands have been added for the impair mode:
- proba no drop: replaces the former "probability" command.
  Percentage of forwarded packets. So 99.5 means 0.5% of packet drop.
- proba delay
  Percentage of delayed packets for the impair mode.
- proba duplicate
  Percentage of duplicate packets.

Similar parameters are supported within the config files:
- proba no drop
- proba delay
- proba duplicate

Note: it is recommanded to use the signature when measuring packet
misorder, as otherwise unexpected packet would cause miscounts.
