The kernel driver unloading/loading code is Linux specific; replace it
with stubs on FreeBSD for now.

Drop the special-case preprocessor definition for PCI access library now
that config.h is available with an equivalent SPDK_CONFIG_PCIACCESS
define.

This allows the custom UIO hotplug driver to be used as well as the
uio_pci_generic driver.

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.

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

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.

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.

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.
