net/ifstated update

[Matthew George]

I just filed a PR (ports/80667) to bring ifstated in line with the latest 
OpenBSD sources.  The only really visible changes should be those dealing with 
the config file grammar.  From their cvs commit message:

<quote>
Simplify the ifstated syntax:

  "carp0 link up" => carp0.link.up
  "and"           => &&
  "or"            => ||

* Allow one line actions after if statements without braces.
* Remove unecessary parentheses in the example config.
</quote>

The example config reflects these changes ... let me know if you have any 
problems with it once it's committed.
