The first version of the Linux kernel NVMe-oF initiator had
a bug when reporting queue size where it was off by 1. We
had a workaround to deal with this. Now that the kernel
has been fixed, remove the workaround.

Register all spdk_malloc() memory regions as ibv_mr in a spdk_mem_map
so we can look up the RDMA key for the user's buffer and pass it in the SGL
directly, rather than copying through a pre-registered bounce buffer.

Change SCSI device configuration format from "DevX LUN0" to "Dev X LUN0"
This allow checking configuration against silly errors when device
number is out of range.
Also assert exactly only one LUN is given.

The send completions must be processed prior to the
recv completions. However, if the completion queues
are separate this leaves a small window where
a send+recv completion arrive between polling
the send_cq and the recv_cq, resulting in the code
seeing the recv completion prior to the send
completion.
By combining the completion queues, this eliminates
any potential gap. The send completion will always
be processed before the recv completion.

Previously, if the maximum number of virtual namespaces had already been
reached, adding a bdev to a subsystem would claim it without actually
adding it to the ns_list array.

when we handle the read command which need split, we need make
sure all the subtasks to be handled if one of the subtask failed,
this will make sure the command have chance return back to initiator.

Since we know the queue depth that we will be using during the test,
request that as the queue size when attaching to NVMe controllers.
Reserve one extra queue entry above the expected queue depth since NVMe
queues must always have one entry free to distinguish between queue
empty and queue full cases.

This patch adds a library, application and test scripts for extending
SPDK to present virtio-scsi controllers to QEMU-based VMs and
process I/O submitted to devices attached to those controllers.
This functionality is dependent on QEMU patches to enable
vhost-scsi in userspace - those patches are currently working their
way through the QEMU mailing list, but temporary patches to enable
this functionality in QEMU will be made available shortly through the
SPDK github repository.

This avoids registering PMDs that are not used by a given
application. For example, an app may wish to *not* use
ioat - in this case, ioat PMD would not be registered with
DPDK, and we would not waste time probing these devices
when probing other devices like NVMe.
