If we created /mnt/huge due to no hugetlbfs mount point existing, we
should also use that path in the chown step for VFIO.

This scripts adds new parameter "status", which shows extra
information about devices connected to the system:
- Numa node on which device is located
- Currently bound driver
- Device name in OS if available

Default is still 1024 2MB huge pages, but user can
override this by setting a different value in the
environment.

In some circumstances, no utmp entry is available, so logname fails.
In particular, gnome-terminal no longer creates a utmp entry:

As a workaround, try $SUDO_USER - the use case here is to determine
the (unprivileged) user name so we can give them ownership of
certain files, so this is usually the right thing to use anyway.
If we are not running under sudo, the caller should have passed the
username as a parameter to scripts/setup.sh anyway, since we can't
reliably determine which user is intended.
Also check if username is actually set before using it to run chmod - it
is possible that the scripts/setup.sh caller does not want to provide
access to an unprivilieged user and just wants to run everything as
root.

Fix typo in checking for mounted hugepages and replace expr with
arithmetic context as expr is returning error when expression is zero.

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.

Allocate larger contiguous regions (but the same amount of total

This increases the largest contiguous region available for any single
object (e.g. DPDK mempools) from 32 MB to 64 MB.

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

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.
