You can reassemble all TCP segments up to the segment with the FIN bit
set by using the method of TCP reassembly mentioned in section 2.7.2 of
doc/README.developer.  The one change you need to make to that sample
code is to change DESEGMENT_ONE_MORE_SEGMENT to DESEGMENT_UNTIL_FIN.

The method above will work the same for packets in a capture file as
well as during a live capture.
