44e60dc47d build: consolidate library outputs in build/lib
Make it easier to use SPDK libraries by putting them all in a single
directory that can be added with -L rather than scattered around the
source tree.

fcb00f3780 nvme: expand probe information to a struct
spdk_nvme_probe() will now provide a struct spdk_nvme_probe_info to the
probe and attach callbacks in place of the PCI device pointer.

This struct contains the useful information that could be retrieved from
the PCI device during probe.

The goal of this change is to allow expansion of the probe information
in the future when other transports (specifically, NVMe over Fabrics)
are added that do not necessarily use PCI addressing or device IDs.

0dd80395f3 env: Move pci.c from util to env
This allows users to swap their PCI library from
libpciaccess/dpdk to another mechanism using the standard
method for swapping out the env library.

a30b5532cb memory: Rename to env
The new env library will wrap all third-party library
calls and be easily swappable with alternate implementations
at build time. For now, it's just the memory library
renamed.

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.

df56ab7711 examples/nvme/arbitration: simplify log page allocation
spdk_nvme_ctrlr_cmd_get_log_page() now allocates a physically contiguous
buffer internally, so the caller does not need to provide special
DPDK-allocated memory.

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>
