Introduce new classify() method that uses AVX2 instructions. >From my measurements: On HSW boards when processing >= 16 packets per call, AVX2 method outperforms it's SSE counterpart by 10-25%, (depending on the ruleset). When build with the compilers that don't support AVX2 instructions, make rte_acl_classify_avx2() do nothing and return an error. At runtime, if librte_acl was build with the compiler that supports AVX2, this method is selected as default one on HW that supports AVX2.
