allow DSA device to async offload crc32 calculation in nvmf-TCP
This patch can use DSA to accelerate crc32 computation, making
the io performance of TCP paths using crc32 approach the io
performance of TCP paths that do not use crc32.
Using SLIST to minimize the performance drop. SLIST has less
operation compared to TAILQ.
Thinking about memory thrashing, we should use the same memory as
possible to receive new PDUs. So, insert newly freed PDU in to head
is better.
The performance drop is within 1% compared to the TCP path without

In NVMe/TCP target, the socket low water mark is set to
sizeof(struct spdk_nvme_tcp_common_pdu_hdr), which is 8 bytes.
In corner test, there might be 4 bytes data packet sent to
NVMe/TCP target, after that, if there is no more data sent to
the same socket, the 4 bytes won't be read by NVMe/TCP target
qpair thread. Because of this, there is a IO request didn't
complete in initiator. Then, if manual call the readv function to
read the 4 bytes for the pdu in target, the io request complete
normally in initiator. It seems like the pdu might be split,
and in the situation, the IO request will not complete until

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.

R2Ts can cause cmds to be submitted to the target
layer in a different order than they were received
from the host. Normally this is fine, but not for
fused commands.
So track fused commands as they reach
nvmf_tcp_req_process(). If we find a pair of sequential
commands that don't have valid FUSED settings (i.e.
NONE/SECOND, FIRST/NONE, FIRST/FIRST), we mark the
requests as "fused_failed" and will later fail them
just before they would be normally sent to the target
layer.
When we do find a pair of valid fused commands (FIRST
followed by SECOND), we will wait until both are
READY_TO_EXECUTE, and then submit them to the target
layer consecutively.
This fixes issue #2428 for TCP transport.

This patch adds support for using zero-copy operations to execute IO
requests in the TCP transport. Of course, they're only used if the
underlying bdev supports them. Additionally, only requests with no
in-capsule-data can be executed using this mechanism.
Added several new states to accommodate for the difference in a way
zero-copy is handled. Also, these flows very depending on the type of a
request (read or write). It stems from zero-copy semantics: to perform
a write we need to wait for zcopy_end completion, while for reads
zcopy_end can only be submitted once we send all of the requested data
to the host.

The tracepoint passes qpair pointer as an argument, while not specifying
it in its definitions, which makes the following assertion to fail:
trace.c:83: _spdk_trace_record: Assertion `0 && "Unexpected number of tracepoint arguments"' failed.

Not every transport requires accept poller - transport specific
layer can have its own policy and way of handling new connection.
APIs to notify generic layer are already in place
- spdk_nvmf_poll_group_add
- spdk_nvmf_tgt_new_qpair
Having accept poller removed should simplify interrupt mode impl
in transport specific layer.
Fixes issue #1876

When no optimal poll group exists for a qpair,
assignment for round robin happens in spdk_nvmf_tgt_new_qpair().
RDMA transport implments the logic for this assignment in
nvmf_rdma_get_optimal_poll_group().
TCP relied on the spdk_nvmf_tgt_new_qpair() instead.
This resulted in race condition when looking up and assigning
optimal poll groups - see #2113.
To remedy that, TCP now follows the same pattern as RDMA.
Next patch will improve the sock map lookup to fix the #2113.

Some of our tpoints have a name exceeding 24 characters.
Althought this is not problem for SPDK, it might cause
confusion, because error messages are printed.
Tpoints regstered inside fc.c had their _REQ_ part removed,
since it was used in all of them.

If a response is returned prior to _nvmf_request_complete being called then the cid in the response is
not set correctly and the PDU state is not reset which causes a hang and the PDU state machine is
expecting more data but none will be sent. There are two cases where this can occur:
1) If the request is bi-directional
2) If nvmf_tcp_req_parse_sgl returns an error (e.g max_io_size exceeded)

Now that the trace library can handle multiple arguments, there's no
point in passing 0 for tracepoints that don't have any arguments. This
patch removes all such instances. It allows us to to verify that
`spdk_trace_record()` was issued with the exact number of arguments as
specified in the definition of the tracepoint.
