Re: epan_t and capture_file

Yes I meant "UI code of some sort".   You know, in case someone submits a Bugzilla ticket for wanting "timeline view in 
TShark".  Then I guess the data computation could be refactored to the ui directory over the qt one.

I mostly wanted to show that not all data computation needs to be done in a dissector and that we need additional APIs 
to expose that data.  While I've tried to move a lot of "protocol specific knowledge" out of the UI, this particular 
feature (at least at the moment) is very tied to a specific dissector.  Otherwise just expanding the "packet/color 
summary scroll bar" might be an option.

By which you presumably mean "UI code of some sort vs. dissector", because...

...*tabular* statistics should, by and large, have as little GUI code of their own as possible, preferably none - that 
way, the tabular statistic can be used in TShark (write the table to the standard output) and in whatever GUIs are 
being used for Wireshark (show a table via the GUI) and....
