examples/tep_term: initialize VXLAN sample
This patch creates the virtio devices management mechanism. These functions are from the vHost example, which include: - virtio device creation. - virtio device destroying. - virtio device maintenance. Signed-off-by: Jijiang Liu <jijiang.liu@intel.com> [Thomas: remove unused function validate_nb_devices()] [Thomas: add maintainers section]
