Patch to implement decoding LANforge protocol

Build Information:
Latest SVN
--
My company makes the LANforge network traffic generation tool to be used for
network performance testing.  I would like to add support to Wireshark to have
it be able to decode the packets properly.

LANforge is a network test tool, so it can run on any IP port.

The LANforge payload header can be inside of TCP or UDP packets, and is defined
as:

#define BTBITS_HDR_MAGIC 0x1a2b3c4d

struct btbits_ip_pkt_hdr {
   uint32 crc; 
   uint32 magic; /* helps pkt sniffers know it's LANforge pkts */
   uint16 src_session_id; /* id of sender */
   uint16 dst_session_id; /* id of receiver */
   uint16 payload_len;
   uint16 payload_pattern;
   uint32 seq_num;
   uint32 tx_time_s;  /* second portion of timestamp */
   uint32 tx_time_ns;  /* nano-second portion of timestamp */
};
