a6dbe3721e update Intel copyright notices
per Intel policy to include file commit date using git cmd
below.  The policy does not apply to non-Intel (C) notices.

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.

488570ebd4 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.

336505abbf lib/ftl: use per-io_channel write buffers
Replaced single global write buffer with the per-io_channel write
buffers.  This means that the "rwb" module and all of its references
were removed and replaced with the recently added interfaces.

e9a236d275 ftl: Initial headers
This patch introduces core structures required for implementing FTL on
top of Open Channel drives. The Open Channel specification describes raw
access to the media on the SSD. The FTL consumes that API and exposes a
block device interface.

The implementation is based on the revision 2.0 of the Open Channel SSD
specification.
