GH-250: Improve/cleanup VXLAN decapsulation support

Browse source 
* Better parsing/error-checking of VXLAN and encapsulated packet headers

* Add/implement the "vxlan_packet" event

* Add "Tunnel::vxlan_ports" option to tune the set of VXLAN ports to
  analyze/decapsulate

* Add "Tunnel::validate_vxlan_checksums" option to allow for tuning of how
  checksums associated with the outer UDP header of a possible VXLAN
  tunnel are handled
