Instead of the next_sge callback returning the physical address
directly, make it return the virtual address and convert to physical
address inside the NVMe library.
This is necessary for NVMe over Fabrics host support, since the RDMA
userspace API requires virtual addresses rather than physical addresses.
It is also more consistent with the normal non-SGL NVMe functions that
already take virtual addresses.

Custom bdev modules can return any SCSI status and SCSI sense
information to a host by this patch. This is usefull when a custome bdev
module detect an error in the module and need to return meaningful
information to a host.
Function pointers will not work for the DPDK multi-process model (they
can have different addresses in different processes), so define a
transport enum and dispatch functions that switch on the transport type
instead.

This enables using SPDK within a larger process that
is SPDK-centric. In this case the process may start
SPDK and then wish to stop it explicitly (without a
signal).
While here, remove an incorrect comment - DPDK mempools
can be used from non-DPDK threads. Also set the
g_shutdown_event to NULL after it is called. After the
event executes, the event is freed and is no longer valid.

Since we are usually going to be removing multiple events from the queue
at once, use the DPDK burst dequeue interface to improve efficiency.
Also rework the event queue runner to always process a fixed maximum
number of events per timeslice for simplicity. This removes the
rte_ring_count() call from the hot path and improves fairness between
events and pollers.
Now that events are dequeued in bulk, we can also put the event objects
back into the mempool in bulk. Add an env wrapper around
rte_mempool_put_bulk() and use it to free all of the events at once.
Basic performance benchmark using test/lib/event/event/event -t 10
is improved: previously ~40 million events per second, now ~46 million
events per second.

Instead of searching /sys for devices and checking which
driver happens to be loaded, use lspci. The lspci tool is
a bit smarter - it knows which driver is loaded now but
also which driver is the default driver the kernel wants
to load for that type of device. It's that default that
we need.

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.

- Split the part that gets a PCI device's address into its own function,
spdk_pci_device_get_addr(). This is useful outside of the comparison
function and is orthogonal to comparing addresses.
- Make the comparison function take two addresses instead of a device
and an address. The more general form will be useful with addresses
that are not directly associated with a device. Because of this, also
rename the function from spdk_pci_device_compare_addr() to
spdk_pci_addr_compare().
- Return a signed value similar to strcmp() so that addresses can be
ordered, not just compared for equality.
