LOG_DEBUG is a symbol defined by POSIX, so if sys/log.h
is included the symbols conflict.
We'll need to push this patch to upstream DPDK too.

Since we keep a copy of DPDK vhost library, the header file don't
have dependency on DPDK vhost library.

The contents of struct spdk_scsi_lun don't need to be part of the public

Fix up all existing spacing errors in comments and add an automated
check for patterns like /*comment*/.

Vhost needs to register memory given by guest in VFIO container to be
able to do any DMA using this memory.
Currently DPDK doesn't provide any interface to handle guest memory, so
for now lets find container fd in /proc/self/fd/ directory and provide
some VFIO internal API that finally should extend DPDK API.

First step is do not destroy an existing device in
vhost_user_set_mem_table(). This is because we may
still be processing I/O via INT13 while QEMU is setting
up the mem tables for OS boot.
The primary part of this patch though is to defer
using the new mem table until after we receive the
first SET_VRING_ADDR message. SET_VRING_ADDR will be
sent by QEMU when guest OS virtio-scsi driver starts
initialization. At this point it is safe to invalidate
the old mem tables because there will be no more
INT13 I/O at this point.

This enables the vhost library to build on systems missing the (fairly
recent) linux/virtio_scsi.h header.

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.

SPDK_COUNTOF works like sizeof, except it returns the number of elements
in an array instead of the number of bytes.

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.
