NVMf target reports copy command support if all bdevs in the subsystem
support copy IO type. Maximum copy size is reported for each namespace
independently in namespace identify data. For now we support just one
source range.
Note, that command support in the controller is initialized once on
controller create. If another namespace which doesn't support copy
command is added to the subsystem later, it will not be reflected in
the controller data structure and will not be communicated to the
initiator. Attempt to execute copy command on such namespace will
fail. This issue is not specific to copy command and applies also to
write zeroes and unmap (dataset management) commands.

In SPDK, declarations have the return type on the same line. Definitions
have the return type on a separate line. Astyle has an option for
enforcing this. Unfortunately, it seems to have two bugs:
1) It doesn't work correctly at all on C++ files.
2) It often fails on functions that return enums, or long type names
Deal with 1) by adjusting the check_format.sh script to only tell astyle
to fix return type line breaks for C files and not C++. Deal with 2) by
adding a few typedefs to work around the problem.

Many open source projects have moved to using SPDX identifiers
to specify license information, reducing the amount of
boilerplate code in every source file. This patch replaces
the bulk of SPDK .c, .cpp and Makefiles with the BSD-3-Clause
identifier.
Almost all of these files share the exact same license text,
and this patch only modifies the files that contain the
most common license text. There can be slight variations
because the third clause contains company names - most say
"Intel Corporation", but there are instances for Nvidia,
Samsung, Eideticom and even "the copyright holder".
Used a bash script to automate replacement of the license text
with SPDX identifier which is checked into scripts/spdx.sh.

This is a public header that needs to be accessible to
code outside of the SPDK project. The spdk_internal/
directory does not end up getting packaged - it's just for
headers used by multiple libraries within SPDK.

For ACWU we always set value 1 because bdev holds
information specific for namespace only. This value
actually does not matter because we also set NACWU
which makes ACWU irrelevant. We set ACWU because
NVMe specs requires ACWU != 0 if fused commands
are supported.

This commit provides the capability to install a
custom admin command handler for NVMF.
It can be used to implement or replace NVMe admin commands that
are currently not handled by the NVMF subsystem.
The handler implementation is pretty generic and the handler function
has to figure out what to do with the command based on the bdevs
that are configured for the subsystem.
In cases where admin commands need to be forwarded to an NVMe bdev,
the commit provides functions that allow access to the underlying bdev.
There is an example handler in lib/nvmf/custom_cmd_hdlr.c.

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
command specific info back to the initiator.

When the NVMf controller's flag dif_insert_or_strip is enabled, DIF is
inserted for write I/O and stripped for read I/O, and the corresponding
NVMe-oF initiator should not be aware of the DIF setting of the
backend bdev.
Hence this patch hides the DIF setting of the backend bdev
when the flag dif_insert_or_strip is enabled.
