[dpdk-dev] [PATCH v3] virtio: split virtio rx/tx queue

[Huawei Xie <huawei.xie@intel.com>]

We keep a common vq structure, containing only vq related fields,
and then split others into RX, TX and control queue respectively.

Signed-off-by: Huawei Xie <huawei.xie@intel.com>
---
v2:
- don't split virtio_dev_rx/tx_queue_setup
v3:
- fix some 80 char warnings
- fix other newer version checkpatch warnings

- remove hdr zone allocation for RX queue
v4:
- remove '\n' in PMD_RX_LOG
- fix some conversions between vq and rx/txvq in virtio_dev_free_mbufs
