whenever a message has been reassembled.
The parameters tvb, pinfo and tree are just handed over to tcp_dissect_pdus(). The 4th
parameter is a flag to indicate if the data should be reassebled or not. This could be set according to
a dissector preference as well. Parameter 5 indicates how much data has at least to be available to be
able to determine the length of the foo message. Parameter 6 is a function pointer to a method that
returns this length. It gets called when at least the number of bytes given in the previous parameter
is available. Parameter 7 is a function pointer to your real message dissector.
