6b1e4e732d Drop libpciaccess and switch to DPDK PCI
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.

memory).

b7095d7b00 setup.sh: get hugepages in 64 MB chunks on FreeBSD
This increases the largest contiguous region available for any single
object (e.g. DPDK mempools) from 32 MB to 64 MB.

c83f9378da scripts: merge hugepage config into setup.sh
For now, drop the option to configure the number of hugepages (just use
the default 1024).

55dc5f2131 Add vfio support to scripts.
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.
