bpf: introduce basic Rx/Tx filters

Introduce API to install BPF based filters on ethdev RX/TX path. Current implementation is pure SW one, based on ethdev RX/TX callback mechanism. Signed-off-by: Konstantin Ananyev <konstantin.ananyev@intel.com> Acked-by: Ferruh Yigit <ferruh.yigit@intel.com>

   The BPF Library provides the ability to load and execute
   Enhanced Berkeley Packet Filter (eBPF) within user-space dpdk application.
+  Also it introduces basic framework to load/unload BPF-based filters
+  on eth devices (right now only via SW RX/TX callbacks).
   It also adds dependency on libelf.
