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.

19fec6bb9c nvme: add remove callback to spdk_nvme_probe()
This will allow removal notifications to be propagated to the library
user (e.g. for hotplug).

The callback is currently unused, but this at least prepares the API for
the future hotplug support.

Based on a patch by Dave Jiang <dave.jiang@intel.com>

39cc59635a build: include -lrt and -lpthread in LDFLAGS
Simplify the build rules so that common libraries are always linked.

Also fix up a couple of -lpciaccess instances that should have been
changed to $(PCIACCESS_LIB).

use the SPDK NVMe driver API for basic enumeration and
I/O operations.
