Victor Julien 317376f59d datasets: match on lists of data
Datasets are sets/lists of data that can be accessed or added from
the rule language.

This patch implements 3 data types:

1. string (or buffer)
2. md5
3. sha256

The patch also implements 2 new rule keywords:

1. dataset
2. datarep

The dataset keyword allows matching against a list of values to see if
it exists or not. It can also add the value to the set. The set can
optionally be stored to disk on exit.

The datarep support matching/lookups only. With each item in the set a
reputation value is stored and this value can be matched against. The
reputation value is unsigned 16 bit, so values can be between 0 and 65535.

Datasets can be registered in 2 ways:

1. through the yaml
2. through the rules

The goal of this rules based approach is that rule writers can start using
this without the need for config changes.

A dataset is implemented using a thash hash table. Each dataset is its own
separate thash.

Victor Julien b286c14324 thash: generalize hash table as used in flow
Thread safe hash table implementation based on the Flow hash, IP Pair
hash and others.

Hash is array of buckets with per bucket locking. Each bucket has a
list of elements which also individually use locking.
