Migrate to DPDK 17.11

[Yi-y-yang]

DPDK 17.11 included several bug fixes for bonding device, it also included more vhost and virtio features compared to vhost and virtio implementation in contrail-vrouter, migrating to DPDK 17.11 is the first step we take, later we prefer to use DPDK virtio and vhost library to replace implementations in contrail-vrouter, this will reduce duplicate efforts in virtio and vhost implementation and make full use of DPDK code base.

Migrate from DPDK 17.02 to DPDK 17.11

Main changes:
- port_id from uint8_t to uint16_t
- DPDK 17.11 added some new libraries, so SConscript has some changes
- API changes: log API, ring buffer API, mempool API, etc.
- Fixed indirect ret_mbuf issue in current contrail-vrouter
