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.

e7a09f7c3f usdt: fix bpftrace parse error on arm64
bpftrace reports parse error on arm64:
"parse error:
8@x0 4@[x21, #:lo12:.LANCHOR2]
"
using "nr" to override the default constraints string can fix this.

//the default is:
 stapsdt              0x0000004b       NT_STAPSDT (SystemTap probe descriptors)
    Provider: spdk

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.

4ee3f1bccf usdt: don't emit probes in unit tests
There is no point in producing USDT probes in unit tests and it breaks
the build on some systems:

ctrlr_discovery_ut.o(.note.stapsdt+0x14): error: relocation refers to local symbol "" [102], which is defined in a discarded section
ctrlr_discovery_ut.o(.note.stapsdt+0x90): error: relocation refers to local symbol "" [108], which is defined in a discarded section
ctrlr_discovery_ut.o(.note.stapsdt+0xf8): error: relocation refers to local symbol "" [110], which is defined in a discarded section
ctrlr_discovery_ut.o(.note.stapsdt+0x15c): error: relocation refers to local symbol "" [112], which is defined in a discarded section

Fixes issue #2027.

a4044e77d6 usdt: pass ticks as the first probe argument
This will allow to match and compare the DTrace probes with SPDK traces
as they'll be using the same source for the timestamps.

5a1c74bfa4 usdt: add User Space DTrace support to SPDK
For now, we will keep this disabled by default,
enable with --with-usdt option to the configure
script.  Long-term we will want to enable this by
default, and only disable via configure.

Modules can include spdk_internal/usdt.h and add
probes such as:

SPDK_DTRACE_PROBE2(probe_name, ptr, val);

When USDT is enabled, these will translate to
DTRACE_PROBE2(spdk, probe_name, ptr, val).  When
USDT is disabled, these will translate to nothing.

Later patches will add some probe points to the
nvmf target, some bpftrace scripts, and instructions
for how to successfully capture data with these
probe points and scripts.
