This change allows setting of the NVMe completion queue
CDW0 in spdk_bdev_io_complete_nvme_status.
Before that change, handling of vendor specific NVMe IO
commands was limited since there wasn't a way to return

Init commit for opal vbdev. Opal vbdev is built based on
bdev part module. We split nvme namespace to spdk_bdev_part
with user specified offset and length. And then use this
configuration also to set up locking range for Opal.
Use linked list g_opal_vbdev to track all configuration for
each vbdev. And use g_opal_base to track the part_base for
all vbdevs.
This patch only shows the process for creating/deleting a vbdev
for an opal-enabled nvme ctrlr.

This patch improves management of base->management_channel in code and
fixes potential issue described below. In situation when we want to create
configuration like this:
$rpc_py bdev_ocf_create C1 wt Malloc NonExisting
$rpc_py bdev_ocf_create C2 wt Malloc Core
In current code on C1 vbdev creation we are creating not fully
initialized vbdev_ocf_base for cache (without management channel).
On C2 creation, because in vbdev_ocf_volume_open we are looking for
right base by name, we can grab cache base from C1 and then, there is
possibility, to hit segmentation fault due to uninitialized
mangament_channel.
This patch moves initialisation of managemnet channel to attach
base function and thanks to that we have guarrnte that each copy of
cache base (we have copy in each parent in case of multicore cache)
are valid.

Fixes#962
Issue mentioned above was caused by race between examine on ocf bdev
(which is partially asynhronous) and bdev delete.
This patch adds new ocf bdev state "starting" it means that register
procedure was started, base on this state, we are not allowing to
destruct vbdev during registering path.
Deleting of vbdev will be still possible on started vbdev or when
register procedure are not started yet.

Realted to #957
Normally we are using vbdev_ocf_qcxt allocated by spdk device (ctx_buf),
but after io_device_destroy_cb this context can be freed, so we allocate a
local copy to use for issuing requests on ocf bdev stop. Unfortunately,
in current code we are not freeing it, this patch fix that issue.

Update transaction length wrt to medata size
Change buffers handling in the case of enabled DIF - add function nvmf_rdma_fill_buffer_with_md_interleave to split SGL into several parts with metadata blocks between them in order to perform RDMA operation with appropriate offsets
Add DIF generation before executing bdev IO operation
Add parsing of DifInsertOrStrip config parameter.
Since there is a limitation on the number of entries in SG list (16), the current approach has a limitation on the max transaction size which depends on the data block size. E.g. if data block size is 512 bytes then the maximum transaction size will be 512 * 16 = 8192 bytes.
In adiition, the size of IO buffer (IOUnitSize conf param) must be aligned to metadata size for better perfromance since metadata is treated as part of this buffer. E.g. if the initiator uses transaction size = 4096, data block size on nvme disk is 512 then IO buffer size should be aligned to (512 + 8) which is 4160. In other case an extra IO buffer will be consumed which will increase the number of entries in SGL and in iov.

spdk_pci_device_claim() could create a file on the
filesystem that couldn't be deleted programatically.
It could only be overwritten - e.g. by another spdk
instance - but this didn't really work if that
another instance had less privileges and hence no
access to the previous file.
This is exactly the case we're seeing on our CI when
running SPDK as non-root. In general it's a good idea
not to leave any leftover files, so now we'll delete
the pci claim file when the spdk process exits.
spdk_pci_device_claim() used to return a file descriptor
that could be simply closed to "un-claim" the device.
It'll now return only a return code. The fd will be
stored inside spdk_pci_device and will be closed either
when user calls the newly introduced spdk_pci_device_unclaim(),
or when the device is detached.
We'll still need to clean up those files somewhere in
our test scripts (probably ./setup.sh cleanup) to
clean up after crashed processes or so - but we don't
necessarily want to run such scripts inside the autotest
whenever a non-root spdk is about to be started.

the mempool dequeue is done in a DPDK inline function

Instead, under #ifdef __clang_analyzer__ we'll now

The SPDK application framework defines a list of event subsystem
dependencies. When linking against individual shared libraries, it is
useful for this dependency structure to be codified in the shared
libraries themselves.
For example, when linking a bdev based application against
libspdk_bdev.so, one might wish to only specify this shared object at
link time. However, when you actually run the application, it will fail
to start because it is not linked to the copy and vmd subsystems.
However, once thesedependencies are added, one can effectively link
against only the exact subsystems they need and any dependent subsystems
will be linked in automatically.
