0329c9b5e5 bdev_virtio: added async I/O
Added struct bdev_virtio_io_channel. Virtio bdev io_channel
now creates a poller that listens on vhost-user socket.

157969b60e bdev_virtio: added virtio_scsi_io_ctx
I/O requests are now allocated from bdev_io memory.
virtio_req->iov now points to raw payload, request and response
iovectors are available as separate fields. This solution
should apply for both vhost-scsi and blk.

c2175d2c51 virtio: add initial rev of virtio-scsi initiator bdev module
Supports both PCI mode (for usage in guest VMs) and
vhost-user mode (for usage in host processes).  The rte_virtio
subdirectory contains a lot of code lifted from the DPDK
virtio-net driver.  Most of the PCI and vhost-user code is
reused almost exactly as-is, but the virtio code is drastically
rewritten as the DPDK code was very network specific.

Has been lightly tested with both the bdevio and bdevperf
applications in both PCI and vhost-user modes.

Still quite a bit of work needed - a list of todo
items is included in a README in the module's directory.
