This patch doesn't use it yet but sets up the ability to so that
upcoming unit test pathces can. The next patch will include use
of wrap in one nvme UT and then following that the wrap and
today's use of globally controlled stubs will be morphed into a
simple mock type capability for spdk unit tests.

Add a configure script in the root of the repository
that looks and feels like one that would be generated
by autotools. This script simply generates a CONFIG
file for you, which used to be done by hand.
Now to build SPDK you can do the following:
./configure --with-dpdk=path
make

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 flag prevents the compiler from merging multiple tenative global
variable declarations (e.g. 'int i;' without an assignment) into a
single copy later. In the default (-fcommon) mode, this allows multiple
definitions of an uninitialized global variable to be linked into a
single program without any warnings.

This requires a couple of related changes:
- I/O queue IDs are now allocated by using a bit array of free queue IDs
instead of keeping an array of pre-initialized qpair structures.
- The "create I/O qpair" function has been split into two: one to create
the queue pair at startup, and one to reinitialize an existing qpair
structure after a reset.

This patch also drops support for automatically unbinding
devices from the kernel - run scripts/setup.sh first.
Our generic pci interface is now hidden behind include/spdk/pci.h
and implemented in lib/util/pci.c. We no longer wrap the calls
in nvme_impl.h or ioat_impl.h. The implementation now only uses
DPDK and the libpciaccess dependency has been removed. If using
a version of DPDK earlier than 16.07, enumerating devices
by class code isn't available and only Intel SSDs will be
discovered. DPDK 16.07 adds enumeration by class code and all
NVMe devices will be correctly discovered.

The NVMf target is being refactored to split the RDMA transport-specific
code into its own file. Once this is complete, we should be able to
plug in other transports and build the NVMf target without any RDMA
dependency if desired.
To enable this, change the CONFIG option to RDMA; it still controls
whether the whole NVMf target is built for now, but once the RDMA
dependency is actually made optional, we will be able to build the
generic NVMf target code without libibverbs installed.
