Argus TCP state machine fixes

Hey Rafael,
So I have fixed argus's issues with your very interesting sets of pcaps.
They were a bit confusing at first, even wireshark doesn't really like them
at all, but I've got argus doing well with your specific files.

Because the fixes have changed some basic TCP state machine code, 
which hasn't been modified in quite a while, we'll need some time to test
this logic out.

As a result, I'm releasing the fixes in argus-3.0.7.1, but  not in the
argus-3.0.6 release tree, until a good amount of testing, if at all.

I should have the new argus up later today.
I still have Napatech board support to put into argus, and there are
fixes that I need to add for PF_RING extended support.  These fixes
will be in argus-3.0.7.2 which should come out later this week.

Hope all is most excellent,

Carter
