The information in this file is not useful after the test has finished,
so rather than copying it to the build output directory, just delete it
like all of the other tests using FIO.

This script is testing the SPDK NVMe-oF host and target code, so the
kernel nvme-rdma driver should not need to be loaded.
It is also not running FIO, so it doesn't need to clean up the FIO
job state files.

This allows us to print better error messages when connecting to a
subsystem that exists but does not allow a specific host.
Additionally, we can now return the correct error code for a host that
is not allowed.

Create a new include/spdk_internal directory for headers that should
only be used within SPDK, not exported for public use.

Considering the process can be terminated in the cases like ctrl+c,
kill command or memory fault, the ref is tracked in the per process
structure spdk_nvme_controller_process and whenever there is other
process attaches or detaches the controller, a scan will be issued
to cleanup those unexpectedly exited processes.

This could use some better validation to make sure failures only happen
during the reset, but this at least gets the nightly tests running

This patch is preparation for fixing alloc_len overrun in SENSE 6/10 and
READCAP 6/10. To simplify code forbid usage of iov outside of
scsi/task.c.
This also drop SPDK_SCSI_TASK_ALLOC_BUFFER flag that obfuscate code. As
a replacement assume that if field alloc_len is non zero it mean that
iov.buffer is internally allocated. Functions
spdk_scsi_task_free_data(), spdk_scsi_task_set_data() and
spdk_scsi_task_alloc_data() manage this field.

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.

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.
