This updates the copyright headers to include 2025. I did this by
running gdb/copyright.py and then manually modifying a few files as
noted by the script.

Currently, if frame-filters are active, raw-values is used instead of
raw-frame-arguments to decide if a pretty-printer should be invoked for
frame arguments in a backtrace.
In this example, "super struct" is the output of the pretty-printer:
(gdb) disable frame-filter global BasicFrameFilter
(gdb) bt
#0 foo (x=42, ss=super struct = {...}) at C:/src/repos/gdb-testsuite/gdb/testsuite/gdb.python/py-frame-args.c:47
#1 0x004016aa in main () at C:/src/repos/gdb-testsuite/gdb/testsuite/gdb.python/py-frame-args.c:57
If no frame-filter is active, then the raw-values print option does not
affect the backtrace output:
(gdb) set print raw-values on
(gdb) bt
#0 foo (x=42, ss=super struct = {...}) at C:/src/repos/gdb-testsuite/gdb/testsuite/gdb.python/py-frame-args.c:47
#1 0x004016aa in main () at C:/src/repos/gdb-testsuite/gdb/testsuite/gdb.python/py-frame-args.c:57
(gdb) set print raw-values off
Instead, the raw-frame-arguments option disables the pretty-printer in the
backtrace:
(gdb) bt -raw-frame-arguments on
#0 foo (x=42, ss=...) at C:/src/repos/gdb-testsuite/gdb/testsuite/gdb.python/py-frame-args.c:47
#1 0x004016aa in main () at C:/src/repos/gdb-testsuite/gdb/testsuite/gdb.python/py-frame-args.c:57
But if a frame-filter is active, the same rules don't apply.
The option raw-frame-arguments is ignored, but raw-values decides if the
pretty-printer is used:
(gdb) enable frame-filter global BasicFrameFilter
(gdb) bt
#0 foo (x=42, ss=super struct = {...}) at C:/src/repos/gdb-testsuite/gdb/testsuite/gdb.python/py-frame-args.c:47
#1 0x004016aa in main () at C:/src/repos/gdb-testsuite/gdb/testsuite/gdb.python/py-frame-args.c:57
(gdb) set print raw-values on
(gdb) bt
#0 foo (x=42, ss=...) at C:/src/repos/gdb-testsuite/gdb/testsuite/gdb.python/py-frame-args.c:47
#1 0x004016aa in main () at C:/src/repos/gdb-testsuite/gdb/testsuite/gdb.python/py-frame-args.c:57
(gdb) set print raw-values off
(gdb) bt -raw-frame-arguments on
#0 foo (x=42, ss=super struct = {...}) at C:/src/repos/gdb-testsuite/gdb/testsuite/gdb.python/py-frame-args.c:47
#1 0x004016aa in main () at C:/src/repos/gdb-testsuite/gdb/testsuite/gdb.python/py-frame-args.c:57
So this adds the PRINT_RAW_FRAME_ARGUMENTS flag to frame_filter_flag, which
is then used in the frame-filter to override the raw flag in enumerate_args.
Then the output is the same if a frame-filter is active, the pretty-printer
for backtraces is only disabled with the raw-frame-arguments option:
(gdb) enable frame-filter global BasicFrameFilter
(gdb) bt
#0 foo (x=42, ss=super struct = {...}) at C:/src/repos/gdb-testsuite/gdb/testsuite/gdb.python/py-frame-args.c:47
#1 0x004016aa in main () at C:/src/repos/gdb-testsuite/gdb/testsuite/gdb.python/py-frame-args.c:57
(gdb) set print raw-values on
(gdb) bt
#0 foo (x=42, ss=super struct = {...}) at C:/src/repos/gdb-testsuite/gdb/testsuite/gdb.python/py-frame-args.c:47
#1 0x004016aa in main () at C:/src/repos/gdb-testsuite/gdb/testsuite/gdb.python/py-frame-args.c:57
(gdb) set print raw-values off
(gdb) bt -raw-frame-arguments on
#0 foo (x=42, ss=...) at C:/src/repos/gdb-testsuite/gdb/testsuite/gdb.python/py-frame-args.c:47

This commit is the result of the following actions:
- Running gdb/copyright.py to update all of the copyright headers to
include 2024,
- Manually updating a few files the copyright.py script told me to
update, these files had copyright headers embedded within the
file,
- Regenerating gdbsupport/Makefile.in to refresh it's copyright
date,
- Using grep to find other files that still mentioned 2023. If
these files were updated last year from 2022 to 2023 then I've
updated them this year to 2024.
I'm sure I've probably missed some dates. Feel free to fix them up as
you spot them.

This commit is the result of running the gdb/copyright.py script,
which automated the update of the copyright year range for all
source files managed by the GDB project to be updated to include
year 2023.

This commit brings all the changes made by running gdb/copyright.py
as per GDB's Start of New Year Procedure.
For the avoidance of doubt, all changes in this commits were
performed by the script.

While reviewing a patch sent to the mailing list, I noticed there are few
places where python code checks if a variable is 'None' or not by using the
comparison operators '==' and '!='. PEP8[1], which is used as coding standard
in GDB coding standards, recommends using 'is' / 'is not' when comparing to a
singleton such as 'None'.
This patch proposes to change the instances of '== None' by 'is None' and
'!= None' by 'is not None'.

Re-format all Python files using black [1] version 21.4b0. The goal is
that from now on, we keep all Python files formatted using black. And
that we never have to discuss formatting during review (for these files
at least) ever again.
One change is needed in gdb.python/py-prettyprint.exp, because it
matches the string representation of an exception, which shows source
code. So the change in formatting must be replicated in the expected
regexp.
To document our usage of black I plan on adding this to the "GDB Python
Coding Standards" wiki page [2]:
--8<--
All Python source files under the `gdb/` directory must be formatted
using black version 21.4b0.
This specific version can be installed using:
$ pip3 install 'black == 21.4b0'
All you need to do to re-format files is run `black <file/directory>`,
and black will re-format any Python file it finds in there. It runs
quite fast, so the simplest is to do:
$ black gdb/
from the top-level.
If you notice that black produces changes unrelated to your patch, it's
probably because someone forgot to run it before you. In this case,
don't include unrelated hunks in your patch. Push an obvious patch
fixing the formatting and rebase your work on top of that.
-->8--
Once this is merged, I plan on setting a up an `ignoreRevsFile`
config so that git-blame ignores this commit, as described here:
https://github.com/psf/black#migrating-your-code-style-without-ruining-git-blame
I also plan on working on a git commit hook (checked in the repo) to
automatically check the formatting of the Python files on commit.

This commit applies all changes made after running the gdb/copyright.py
script.
Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.
