* Switch to yearless copyright per FB policy
* Fix up SPDX-License-Identifier lines in `contrib/linux-kernel` sources
* Add zstd copyright/license header to the `contrib/linux-kernel` sources
* Update the `tests/test-license.py` to check for yearless copyright
* Improvements to `tests/test-license.py`
* Check `contrib/linux-kernel` in `tests/test-license.py`
both `--long-commmand=arg` and `--long-command arg`
are supported by macro `NEXT_FIELD()`
so that the long-command only needs to be listed once.
This extends the syntax to support new syntaxes like
`-o=FILE` or `-D=dict`,
though there is no need to advertise this capability for the time being.
Also : added `NEXT_UINT32()`,
which is wrapper around `NEXT_FIELD()`
to read integer parameters.
Use the wrapper to new field, such as `--memlimit`
which can now support both syntaxes too.
for --patch-from origin
and --filelist list
Also : removed some constrained syntax tests,
as the new argument parsing syntax is more permissive.
For example :
zstd file -of dest
used to be disallowed.
It's now allowed, and understood as:
zstd file -o dest -f
this patch reduces complexity associated with
commands requiring a separated arguments
such as :
-o filename
-D dictionary
--output-dir-flat dir
--output-dir-mirror dir
It used to be a multi-stage process with explicit context,
it's now simplified as a single macro.
Thanks to this simplification,
separated arguments logic has also been extended to
--patch-from XXX
--filelist XXX
which extends existing capability using =XXX
--patch-from=XXX
--filelist=XXX
Separated argument is useful for filenames and directories,
as it benefits from shell expansion
such as ~/dir/file
where the ~ is automatically translated by the shell.
In contrast --long-command=FILE does not interpret FILE,
so ~/ is transmitted as is to the main() function,
generally resulting in incorrect file name.
This adds support for just showing the version string
without the full welcome message if the log level is
less than the default. That means that you pass -q once
and you will just see "1.4.5".
This makes it easier to parse in scripts.

The copyright in `threading.{h,c}` is not changed because it comes from
zstdmt.
