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.

8dd1cd2104 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.

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.

2515621184 bdev/delay: Find delay_bdev directly from g_delay_node list
spdk_bdev_get_by_name() uses RB tree and is fast. However it is not
secure from race condition. We can use spdk_bdev_open_ext() instead
but what we want to get is not spdk_bdev but vbdev_delay.
vbdev_delay is managed by the g_delay_nodes list.

The g_delay_nodes includes only vbdev_delay. Even if its performance
is O(N), it is more intutive, more secure, and small list.

So replace spdk_bdev_get_by_name() by simple list traversal.

d1024c4bc6 bdev/delay: zero-copy support
This patch adds support for zero-copy operations in the delay bdev.
They use the same delay values as regular IO operations:
 - (avg|p99)_read_latency for zcopy_start with populate=true,
 - (avg|p99)_write_latency for zcopy_end with commit=true.

All other zcopy operations (e.g. zcopy_start with populate=false) are
not delayed.

vbdev_delay_register() gets bdev name instead of bdev pointer as a

spdk_bdev_open_ext().

The purpose is to fix the race condition due to the time gap
between spdk_bdev_get_by_name() and spdk_bdev_open(). A bdev pointer
is valid only while the bdev is opened.

Resize event is not supported for now.

virtual device upon the base device can be opened on another
thread. At the time of virtual device destruction, the base
device is also closed at the thread where opening the virtual
device, it is actually different than the original thread where
this base device is opened through the JSON configure.

device is opened and then later route it back to handle the base
device close operation.
