- Rebase on newest code.
This patch set depends on below patch sets:

Add multi queue support for virtio-user virtual port. Patch 1 adds vhost
user adapter communications for enable/disable queues. Patch 2 adds features
check for multi queue and provides a method for virtio-user driver to
enable/disable queues. Patch 3 partially implements ctrl-q to handle
VIRTIO_NET_CTRL_MQ_VQ_PAIRS_SET command from PMD.
Test case:
1. start testpmd with a vhost-user port:
$ TESTPMD -c 0x7 -n 4 --socket-mem 1024,0 --no-pci \
--vdev 'eth_vhost0,iface=/tmp/sock0,queues=2' \
-- -i --rxq=2 --txq=2 --nb-cores=2
2. start testpmd with a virtio-user port:
$ TESTPMD -c 0x70 -n 4 --socket-mem 1024,0 --no-pci --file-prefix=testpmd \
--vdev=virtio-user0,mac=00:01:02:03:04:05,path=/tmp/sock0,queues=2 \
-- -i --rxq=2 --txq=2 --nb-cores=2 --txqflags=0xf01 --disable-hw-vlan
3. use below commands to see if all queues are working:
testpmd> show port xstats all

virtio-user: use virtual address in cq
virtio-user: add mq in vhost user adapter
virtio-user: add ctrl-q and mq in device emulation
virtio-user: handle ctrl-q in driver
