[Bro] Error in TCP data length calculation

Hi all,

I tried to access the field tcp_hdr::dl in one of my bro scripts in
order to obtain the TCP payload length. But all the values calculated by
bro seemed to be way too big.

This is due to a missing ntohs() call on the total length field in the
IP-Header in Session.cc. I attached a patch against bro-1.4 that should
fix the problem.

Best regards,
