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.

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.

This converts some, but not all, usage of rte_mempool
to spdk_mempool. The remaining rte_mempools use features
we elected not to expose through spdk_mempool such as
constructors, so that will need to be revisited.

Use the env library to perform all memory allocations
that previously called DPDK directly.

This allows users to swap their PCI library from
libpciaccess/dpdk to another mechanism using the standard
method for swapping out the env library.

This allows users to swap out SPDK's third party
libraries for an implementation based on their own
framework.

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.

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.

While here, also mention that the plugin only supports

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.

Use the knowledge that both the source and destination of
nvme_copy_command() are aligned to emit the aligned variants of the
SSE2/AVX mov instructions.

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).
