netdev-dpdk: Add support for DPDK 16.07

This commit introduces support for DPDK 16.07 and consequently breaks
compatibility with DPDK 16.04.

DPDK 16.07 introduces some changes to various APIs. These have been
updated in OVS, including:
* xstats API: changes to structure of xstats
* vhost API:  replace virtio-net references with 'vid'
