net/i40e: add private APIs for flow filtering

The legacy filter API will be superseded by rte_flow.
There are also several small features which can not be
implemented in rte_flow. This patch re-implemented these
features as private API.
Three APIs are added:
rte_pmd_i40e_get_fdir_info.
rte_pmd_i40e_get_fdir_stats.
rte_pmd_i40e_set_gre_key_len.

Updated i40e PMD with new features and improvements, including:
* Supported cloud filter for IPv4/6_TCP/UDP/SCTP with SRC port only or DST port only.
* Re-implemented get_fdir_info and get_fdir_stat in private API.
* Re-implemented set_gre_key_len in private API.
* **Added DOCSIS protocol to rte_security.**
