Add vfio-user transport support based on existing virtio client
library.
Test steps using bdevperf:
Start `spdk_tgt` with created virtio_blk device:
1. build/bin/spdk_tgt
2. scripts/rpc.py bdev_malloc_create -b malloc0 $((512)) 512
3. scripts/rpc.py vfu_virtio_create_blk_endpoint vfu.0 --bdev-name malloc0 \
--cpumask=0x1 --num-queues=2 \
--qsize=256 --packed-ring
Start `bdevperf`:
1. test/bdev/bdevperf/bdevperf -r /var/tmp/spdk.sock.1 -g -s 2048 -q 128 -o 4096 \
-w randread -t 30 -m 0x2
2. scripts/rpc.py -s /var/tmp/spdk.sock.1 bdev_virtio_attach_controller --dev-type blk \
--trtype vfio-user --traddr vfu.0 VirtioBlk0
3. test/bdev/bdevperf/bdevperf.py -s /var/tmp/spdk.sock.1 perform_tests
