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.

A C++ compiler is required to build the trace app. Add it to the list of
packages to install.

For now, drop the option to configure the number of hugepages (just use
the default 1024).

This is very minimal and needs to be expanded, but
at least point the users at the examples as the next
place to go.

Tweak the build instructions slightly to make them simpler to follow.
If someone is reading the instructions top to bottom, the section about
how to build SPDK assumes the current directory is the top-level SPDK
repository, but if the reader just finished building DPDK, they would be
in the DPDK directory.

cleanup.sh and unbind.sh have been combined into a single
setup.sh that takes one optional parameter (reset). If no
parameter is given, the script will automatically bind
all NVMe and IOAT devices to either uio_pci_generic
or vfio-pci, as appropriate based on IOMMU settings. If
the reset parameter is given, the devices will be bound back
to the appropriate kernel drivers.

libaio is required by examples/nvme/perf on Linux, so add it to the list

DPDK's install target now requires DESTDIR to be set, so change the
build instructions to set DESTDIR=. to match previous behavior.

This is very convenient. It also works from subdirectories, as
long as you adjust the relative path you pass appropriately.
