low level objects are extracted to be used directly.

Use SPDX license identifiers in remaining files.

There are a few places we can replace existing license
text with SPDX license identifiers, that did not match
the auto-replacement script in the previous patch.

Make those replacements manually in this patch instead.

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.

Remove year from copyright headers.

Also add a space between Copyright and (c).

The copyright year can be determined using git metadata.

Also remove the duplicated "All rights reserved." - every instance of
this line already has a corresponding "All rights reserved" immediately
below it, except for examples/ioat/kperf/kmod/dma_perf.c, where I have
added it manually.

Performed using this command:

git ls-files | xargs sed -i -e 's/Copyright(c) \(.*\) Intel Corporation. All rights reserved./Copyright (c) Intel Corporation./'
