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.

9b172afdb6 ioat: clear the internal channel error register on reset
I/OAT device will refuse to resume from the Halted
state until we clear both CHANERR and CHANERR_INT
registers.

We only cleared CHANERR so far. So after the I/OAT
device encountered an error, SPDK would not be able
to initialize it ever again unless it's rebound to
the ioatdma driver.

Unlike CHANERR, CHANERR_INT is only accessible through
PCI config space.

CHANERR_INT is only available on I/OAT devices with
version < 3.3.

c02b179490 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./'

it.  Detect whether static_assert is available in <assert.h> and if not,

625fcb9ed3 ioat: add a union of all descriptor types
The ioat library currently only supports DMA copy operations, but the
hardware can do other types of transfers.  Add a union of the hardware
descriptor structures to enable support for the other operations in the
future.

Also add a generic hardware descriptor type to allow access to the parts
of the descriptor that are common between all types.
