Currently the l3fwd sample app supports LPM and EM lookup methods this
patchset implements the FIB library as another lookup method for l3fwd.
Instead of adding an individual flag for FIB, a new flag '--lookup' has
been added that allows the user to select their desired lookup method.
The flags '-E' and '-L' have been retained for backwards compatibility.

---

v5:
    - Removed runtime checks to ensure desired port is within portmask,
      unused ports are still removed during setup

v4:
    - Changed individual switches for lookup methods to an
      enum for all lookup methods
    - Removed '-F' and introduced '--lookup' flag to select lookup methods
    - Fixed indentation issues
    - Renamed some variables for increased clarity
    - Minor changes to some logic for readability
    - Implemented MAC updating for FIB on non-SSE machines
    - Implemented RFC1812 for FIB on non-SSE machines
    - Added checks to ensure desired port is within portmask

v3: add support for NEON, PPC 64 and machines that do not support SSE,
    NEON or PPC 64.

v2: added the socket header file to fix FreeBSD build.
