    Aho-corasick MPM optimized for the Tilera Tile-Gx architecture.

    Efficient String Matching: An Aid to Bibliographic Search
    Alfred V. Aho and Margaret J. Corasick

    - Started with util-mpm-ac.c:
        - Uses the delta table for calculating transitions,
          instead of having separate goto and failure
          transitions.
        - If we cross 2 ** 16 states, we use 4 bytes in the
          transition table to hold each state, otherwise we use
          2 bytes.
        - This version of the MPM is heavy on memory, but it
          performs well.  If you can fit the ruleset with this
          mpm on your box without hitting swap, this is the MPM
          to go for.

    - Added these optimizations:
        - Compress the input alphabet from 256 characters down
          to the actual characters used in the patterns, plus
          one character for all the unused characters.
        - Reduce the size of the delta table so that each state
          is the smallest power of two that is larger than the
          size of the compressed alphabet.
        - Specialized the search function based on state count
          (small for 8-bit large for 16-bit) and the size of
          the alphabet, so that it is constant inside the
          function for better optimization.

Todo:

Do a proper analysis of our existing MPMs and suggest a good one based on the pattern distribution and the expected traffic(say http).

Irrespective of whether we cross 2 ** 16 states or not,shift to using uint32_t for state type, so that we can integrate it's status as a final state or not in the topmost byte. We are already doing it if state_count is > 2 ** 16.
Test case-sensitive patterns if they have any ascii chars. If they don't treat them as nocase.
Reorder the compressed alphabet to put the most common characters first.
