df46c41a4c nvme: Unify spdk_nvme_discover and spdk_nvme_probe
They were very close to the same already, so finish the job.

32e838af3c nvme: Remove probe_info, just use transport_id
The probe_info was reduced to just containing a
transport_id, so remove probe_info entirely.

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.

02a17e193e env: Replace DPDK atomics with gcc standard calls
Use standard GCC style atomic operations instead of
the DPDK calls. The DPDK calls end up translating
to the gcc standard inline calls in the generic
case anyway.

7f5b671db7 env: Convert some rte_mempools to spdk_mempools
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.

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.

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.
