Victor Julien fd5a06017d detect: per port and proto rule grouping 
Replace tree based approach for rule grouping with a per port (tcp/udp)
and per protocol approach.

Grouping now looks like:

               +----+
               |icmp+--->
               +----+
               |gre +--->
               +----+
               |esp +--->
               +----+
          other|... |
        +----->-----+
        |      |N   +--->
        |      +----+
        |
        | tcp  +----+   +----+
        +----->+ 80 +-->+ 139+-->
        |      +----+   +----+
        |
        | udp  +----+   +----+
    +---+----->+ 53 +-->+ 135+-->
    |          +----+   +----+
    |toserver
+--->
    |toclient
    |
    +--->

So the first 'split' in the rules is the direction: toserver or toclient.
Rules that don't have a direction, are in both branches.

Then the split is between tcp/udp and the other protocols. For tcp and
udp port lists are used. For the other protocols, grouping is simply per
protocol.

The ports used are the destination ports for toserver sigs and source
ports for toclient sigs.
