8dd1cd2104 check_format: For C files only, fix return type breaks
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.

488570ebd4 Replace most BSD 3-clause license text with SPDX identifier.
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.

04cd292237 nvme/quirk: add MDTS excludes interleaved metadata quirk
The specification for Maximum Data Transfer Size (MDTS) says this field
should include the length of metadata, if metadata is interleaved with the
logical block data.  However, some drives can support MDTS without counting
the interleaved metadata, so for this case SPDK will only use data length
without interleaved metadata length.

014baeb8ef nvme: add support for ZNS zone append vector variant
We already have support for spdk_nvme_zns_zone_append(),
add support for spdk_nvme_zns_zone_appendv() (zone append with
NVME_PAYLOAD_TYPE_SGL).

_nvme_ns_cmd_rw() currently performs verification of the SGL,
if the parameter check_sgl is set. This parameter is set for all
calls with payload of type NVME_PAYLOAD_TYPE_SGL.

In order to be able to perform the same check_sgl verfication on
zone append vectors, we need to refactor _nvme_ns_cmd_rw() a bit.

Setting check_sgl ensures that _nvme_ns_cmd_split_request_sgl() or
_nvme_ns_cmd_split_request_prp() gets called.

These functions will split an oversized I/O into several different
requests. However, they also iterate the SGE entries, verifies that
the total payload size, total SGE entries is not too many, and that
buffers are properly aligned. A proper request will not get split.

For zone append, splitting a request into several is not allowed,
however, we still want the verification part to be done, such that
(e.g.) a non first/last SGE which is not page aligned, will cause
the whole request to be rejected.
(In the case of spdk_nvme_ns_cmd_write(), a non first/last SGE which
is not page aligned will instead cause the request to be split.)

An alternative would be to try to rip out the verification part from
_nvme_ns_cmd_split_request_sgl() and _nvme_ns_cmd_split_request_prp().
However, that is non-trivial, and would most likely end up with a lot
of duplicated code, which would easily get out of sync.

4249dc1010 nvme: account for PRACT when calculating max sectors per transfer
There is a special case when using 8-byte metadata + PI + PRACT
where no metadata is transferred to/from controller.

Since _nvme_ns_cmd_rw() already calculates the proper sector size
using _nvme_get_host_buffer_sector_size(), which takes PRACT into
account, change the sectors_per_max_io calculation to also take
PRACT into account.

This will avoid certain requests that don't need splitting getting
split.

aa6767fb14 nvme: add support for ZNS zone append command
The Zone Append command is an optional command in the Zoned Namespace
Command Set.

Zone Append differs from a regular write, in that the command is not
given an exact LBA of where to write the data.

Instead the user has to set the zslba field to the start of a zone,
and the data will be appended to that zone.

The actual LBA where the data was stored is returned in the
spdk_nvme_cpl, where Dword0 contains 31:00 of the ALBA field,
and Dword1 contains bits 63:32 of the ALBA field.

With some build environments (e.g. clang, see #1613) linking fails with
unresolved references. This is caused by the inclusion of 'unused code'
which is usually discarded by the linker. The 'unused code' contains
references to functions that have not been 'stubbed' out. The failure
can be seen by removing 'LDFLAGS += -Wl,--gc-sections' in
spdk.unittest.mk

Resolved by adding stubs for missing references. These are never called
so return an arbtrary default value.

3306e49e24 nvme: introduce probe context data structure and API
Existing NVMe driver uses a global list g_nvme_init_ctrlrs
to track the controllers during initialization, and internal
function will start each controller in the list one by one
until the list is empty.  We introduce a probe context
and move the global list into the context, with the context
we can enable asynchronous probe API in the next patch, also
this can enable parallel probe feature.

04ee899fcf nvme: improve probe error handling in MP even further
In cases we probe without a specific trid, the underlying
rte_bus_probe() in spdk_pci_enumerate() might fail to
initialize some devices, but still return with code 0,
That's technically correct, as we asked just to probe
devices on the bus and that's what it did. Some devices might
have been initialized, others not. In secondary process we
blindly assumed all devices were probed successfully, which
might have eventually led to assert failures, as current
process was not on the ctrlr->active_procs list.

To fix it, just add an additional check before attaching
the controller in secondary process.

7dff719f7e nvme: optimize layout of struct nvme_payload
Rather than storing nvme_payload::type explicitly, use the SGL reset
function pointer as an indicator: if reset_sgl_fn is non-NULL, then the
payload is an SGL type; otherwise it is a contiguous buffer type.

This eliminates the one-byte type member from struct nvme_payload,
making it an even 32 bytes instead of 33, allowing the removal of the
awkward packing inside struct nvme_request.

6368d6c0f5 nvme: add new spdk_nvme_connect() API to directly attach the ctrlr
With this new API, callers can attach one specific ctrlr identified by
the transport ID directly along with optional ctrlr opts. If connecting
to multiple controllers, it is still suggested to use spdk_nvme_probe()
and filter the requested controllers with the probe callback.

Two primary use cases:
1) connecting to the NVMe-oF discovery controller
2) more straightforward way to connect a specific controller (avoiding
the probe callback)

A typical usage of this API with specific ctrlr_opts:
1. struct spdk_nvme_ctrlr_opts user_opts = {}
2. Call spdk_nvme_ctrlr_get_default_ctrlr_opts(&user_opts, sizeof(user_opts))
3. Modify the content of the initialized user_opts with user required value like
   user_opts.num_io_queues = 8
4. Call spdk_nvme_connect(&trid, &user_opts, sizeof(user_opts))
