Added support for DPDK 19.02 and 19.05

Added support for DPDK 19.02 and 19.05

This includes supporting following API changes
- RTE_VER_... now in rte_config.h instead of rte_version.h
- <rte_ethdev.h> now seems required by <rte_eth_ctrl.h>
- rte_sched_port_pkt_write takes extra argument
- rte_sched_port_pkt_read_tree_path takes extra argument
- enum rte_meter_color replaced by rte_color

The extra argument, sched_port, is initialized based on qos_conf parameters.
Modes such as qinq_encap4 uses sched_port when doing classification, but does
not set qos_conf params. It inherits the sched_port from QoS
