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.

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.

examples/accel/perf: perf tool using the accel framework

Supports SW accel engine, CBDMA accel engine and eventually the DSA
accel engine through common API. Basic functions only are included
here, subsequent patches will add more features as needed. For
example, the verify function is very crude right now.

Tool output was compared to the ioat perf tool w/CBDM and results
are very close although there a small penalty for using the
framework.

For CBDMA, start the app with --wait-for-rpc and run the ioat scan
RPC with desired whitelist. If there are not enough channels
(channels are not a concept in the framework) then SW accel engine
will be used for cores that could not get a channel.

examples/sock/hello_sock: introduce sample application for libsock

This patch introduces sample application to show how to use libsock
and net frameworks in the SPDK.

While SPDK doesn't use client path in any way, for now, it also can
help us to write functional tests for both - client as well as server
paths.

SERVER MODE
-----------
In the server mode this application works like echo server responding
to the connected client with received data.

CLIENT MODE
-----------
In the client mode this application works like a telnet client sending
data from stdin to the server and printing out respose.
