sock: replace sock impl priorities

Instead of using socket priorities, use a macro to set the default
implementation.
POSIX is the simplest impl compared to other sockets in SPDK and it
should be used as default (POSIX is most likely to be present at all
times and has the minimal requirements to work).

Replaced direct calls to the CUnit's functions to run the tests with

a specific test case.

The blob.c unit test wasn't changed, because it runs all tests multiple
times with different parameter combinations, so it cannot be easily
converted. In the future, each such combination could be split into a
separate test suite, which would make it compatible with
spdk_ut_run_tests().

Intel copyrights were not added to files where Intel either had
no contribution ot the contribution lacked substance (ie license
header updates, formatting changes, etc). Contribution date used
"--follow -C95%" to get the most accurate date.

Note that several files in this patch didn't end the license/(c)
block with a blank comment line so these were added as the vast
majority of files do have this last blank line. Simply there for

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.

sock: introduce dynamic zerocopy according to data size

MSG_ZEROCOPY is not always effective as mentioned in
https://www.kernel.org/doc/html/v4.15/networking/msg_zerocopy.html.

Currently in spdk, once we enable sendmsg zerocopy, then all data
transferred through _sock_flush are sent with zerocopy, and vice
versa. Here dynamic zerocopy is introduced to allow data sent with
MSG_ZEROCOPY or not according to its size, which can be enabled by
setting "enable_dynamic_zerocopy" as true.

lib/sock: provide a hint to picking optimal poll group

The process of matching qpair to poll group is split into
two distinct parts that occur on different threads.
See spdk_nvmf_tgt_new_qpair().

This results in a race condition for TCP between spdk_sock_map_lookup()
and spdk_sock_map_insert(), which are called in spdk_nvmf_get_optimal_poll_group()
and spdk_nvmf_poll_group_add() respectively.

Fixes #2113

This patch picks a hint from nvmf_tcp for next poll group,
which is then passed down to spdk_sock_map_lookup().

When matching placement_id exists, but does not have
a poll group assigned - the hint will be used.

CUnit provides a helper macro CU_ADD_TEST() that
simplifies usage of CU_add_test() function.

ut: simplify error handling at initialization

This patch changes the way that unittests initialize.
The new way is shorter and simpler.
It assumes that error during initialization is a fatal error,
but in our cases it always is.

This patch is a followp up to
https://review.spdk.io/gerrit/c/spdk/spdk/+/930

lvol_ut.c is the only test that skipped because
it runs same tests multiple times which is not allowed
by new method.

sock/uring: Add the async network I/O support for socket

This patch is used to add the async network I/O support in
sock layer. If code is configured with I/O uring, --with-uring,
we can use io uring in Linux (version >=5.4-rc3).

PS: We also make VPP's default priority > uring, because
for the iSCSI or sock test linked with VPP. It tests VPP with
a given address (which is not a special VPP can only open address),
so using uring can also listen those address succefully. And if we make
uring with priority > VPP, actually, VPP will not tested in those cases.

Additionally, the current CI pool is not ready for test, we need
wait for the CI system ready. And I test on my local platform, it works.
