lib/jsonrpc: Store pointers to outstanding requests.

Currently a request is only added to a list in jsonrpc
connection structure (stored inside jsonrpc server
data structure), when its response is ready to send.
This means that until that point, we do not have its
pointer available inside jsonrpc server data, so if
a server is shut down, it cannot properly handle that
request. Furthermore, when server's memory is freed
and connection is closed before such a request is sent,
`jsonrpc_server_send_response()` will still try to insert
the request into connection queue, resulting in
heap-use-after-free errors. To remedy that issue, this
patch introduces a new list for outstanding requests and
skips sending responses in case a connection is not
available.

Fixes #3052

test/unit: use spdk_ut_run_tests()

Replaced direct calls to the CUnit's functions to run the tests with
spdk_ut_run_tests(). That way, each test will have the ability to run
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().

git log --follow -C90% --format=%ad --date default <file> | tail -1

and then pull just the 4 digit year from the result.

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
consistency.

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.

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.

jsonrpc: fix received JSON buffer overwrite

The receive buffer and JSON values array are shared across all requests
on one connection. If RPC handlers deferre processing response, do the
lazy decode or capture JSON by pointer instead of copying it then
content of the request array might be overwritten by now. As we don't
have any requirement here we must assert that the received request is
valid till response is finished.

Fix this issue by copying request data and work on the copy. This change
also void the need of having JSON RPC 'id' field releasing over 128
bytes from each spdk_jsonrpc_request.
