Fix issue with port check ordering

The link-free policy may modify the port, so do the port checking
extracted from the link terms at at the end of the link-free policy.

Closes #148.

katnetic: implement dump for local policies.

At the moment there's no way of knowing which switches a local policy
may refer to, so just iterate over the first 40 switch ids and print the
tables.

In the near future, this code should find all the switches the policy
checks for, and only dump those flow tables.

Fix bug in regex_of_policy for certain seq cases

In certain cases, the transformation wasn't using the fact that
sequencing is associative. For example in this program

    (filter switch = 1; port := 1 ;
      (1@1 => 2@1; filter switch = 2; port := 4)); 9@2 => 2@3

the transformation descends to the sequence of the link and the filter
on switch = 2. The link term will create a TP continuation, and the
filter will crate an NL continuation. The sequencing rule for TP, NL
would properly create a NL continuation in this case. But, if this NL
continuation is ever called with None as its second argument (indicating
no link-free policies are available), it will force the TP continuation
to turn the link into a character.

This is exactly what happens once you go up one constructor level,
where you're dealing with this expression:

  `(1@1 => 2@1; filter switch = 2); port := 4`

The left-hand side is the aforementioned NL continuation with the
embedded TP call. Passing that continuation None as its second argument
forced the link to become a character, causing the error.

What this code should have done is create a new NL continuation that
will be able to receive more link-free policies from its context, and
pass those along.

I've added an ascii "truth-table" showing the valid continuation
transitions. In the case of NL, NL, it should always transition to NL,
but just forcing the left-hand side continuation does not ensure that in
the general case. Therefore, you have to wrap the call in the proper
constructor.

Closes #152.
Must start from VLAN ID 1.
Start automaton state numbering from 2

Now it's assumed that all packets outside of the network are on vlan 1,
so start numbering automaton states from 2.
