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.

For existing \file markers, move them to the top of the header and tweak
the wording for consistency.

This patch is used to support spdk_pci_device_cfg read/write
with byte and word size.

Also consistently place the extern "C" before any includes or other
declarations in files that already had it.

Rename all functions with a spdk_ prefix, and provide enough of an API
to avoid apps needing to #include <pciaccess.h>.
The opaque type used in the public API for a PCI device is now
struct spdk_pci_device *.

This is a step toward abstracting PCI access so that libpciaccess can be
swapped out more easily.

This patch did the work to use pci related functions
provided by DPDK.

With CONFIG_PCIACCESS=y in CONFIG file, we can
use libpciaccess library; With CONFIG_PCIACCESS=n
in CONFIG file, we use pciaccess functions provided
in DPDK.

spdk_pci_device_get_dev() needs to access the 'dev' member of a struct
pci_device, but the pointer to the struct is also called 'dev' in the
macro argument list. Change it to something else so the 'dev' member
doesn't get replaced by the macro argument.
This is the minimal bug fix; more cleanup will happen later as the PCI
interface is refactored.

This patch adds Intel NVMe device list and overrides the
supported log pages according to the quirk list.
In particular, the READ_CMD_LATENCY and WRITE_CMD_LATENCY pages are
supported on Intel DC P3x00 devices despite not being listed in the
Intel vendor-specific log page directory.

Also add a space between Copyright and (c).
The copyright year can be determined using git metadata.
Also remove the duplicated "All rights reserved." - every instance of
this line already has a corresponding "All rights reserved" immediately
below it, except for examples/ioat/kperf/kmod/dma_perf.c, where I have
added it manually.
Performed using this command:
git ls-files | xargs sed -i -e 's/Copyright(c) \(.*\) Intel Corporation. All rights reserved./Copyright (c) Intel Corporation./'

This more accurately represents what function it performs.
Also remove pci_device_has_uio_driver() from the public API. Callers
should use pci_device_has_non_uio_driver() instead.

This helps enable FreeBSD, where pciaccess pci_device_has_kernel_driver()
is not functional. The function will return 0 if there is no driver
attached, or the Linux uio or FreeBSD nic_uio driver is attached. It will
return 1 otherwise.
