This patch is the result of running 'isort .' in the gdb directory.
Approved-By: Simon Marchi <simon.marchi@efficios.com>

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.

Running 'black' on gdb fixed a couple of small issues. This patch is
the result.

With python 3.4, I run into:
...
Traceback (most recent call last):^M
File "<string>", line 1, in <module>^M
File
"outputs/gdb.python/py-send-packet/py-send-packet.py", line 128, in \
run_set_global_var_test^M
res = conn.send_packet(b"X%x,4:\x02\x02\x02\x02" % addr)^M
TypeError: Could not convert Python object: b'X%x,4:\x02\x02\x02\x02'.^M
Error while executing Python code.^M
...
while with python 3.6 this works fine.
The type of addr is <class 'gdb.Value'>, so the first thing to try is whether
changing it into a string works:
...
addr_str = "%x" % addr
res = conn.send_packet(b"X%s,4:\x02\x02\x02\x02" % addr_str)
...
which gets us the more detailed:
...
TypeError: unsupported operand type(s) for %: 'bytes' and 'str'
...
Fix this by avoiding the '%' operator in the byte literal, and use instead:
...
def xpacket_header (addr):
return ("X%x,4:" % addr).encode('ascii')
...
res = conn.send_packet(xpacket_header(addr) + b"\x02\x02\x02\x02")
...
Tested on x86_64-linux, with python 3.4 and 3.6, and a backported version was
tested on the gdb-12-branch in combination with python 2.7.

New in this version:
- Add a PY_MAJOR_VERSION check in configure.ac / AC_TRY_LIBPYTHON. If
the user passes --with-python=python2, this will cause a configure
failure saying that GDB only supports Python 3.
Support for Python 2 is a maintenance burden for any patches touching
Python support. Among others, the differences between Python 2 and 3
string and integer types are subtle. It requires a lot of effort and
thinking to get something that behaves correctly on both. And that's if
the author and reviewer of the patch even remember to test with Python
2.
See this thread for an example:
https://sourceware.org/pipermail/gdb-patches/2021-December/184260.html
So, remove Python 2 support. Update the documentation to state that GDB
can be built against Python 3 (as opposed to Python 2 or 3).
Update all the spots that use:
- sys.version_info
- IS_PY3K
- PY_MAJOR_VERSION
- gdb_py_is_py3k
... to only keep the Python 3 portions and drop the use of some
now-removed compatibility macros.
I did not update the configure script more than just removing the
explicit references to Python 2. We could maybe do more there, like
check the Python version and reject it if that version is not
supported. Otherwise (with this patch), things will only fail at
compile time, so it won't really be clear to the user that they are
trying to use an unsupported Python version. But I'm a bit lost in the
configure code that checks for Python, so I kept that for later.

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.

This commits adds a new sub-class of gdb.TargetConnection,
gdb.RemoteTargetConnection. This sub-class is created for all
'remote' and 'extended-remote' targets.
This new sub-class has one additional method over its base class,
'send_packet'. This new method is equivalent to the 'maint
packet' CLI command, it allows a custom packet to be sent to a remote
target.
The outgoing packet can either be a bytes object, or a Unicode string,
so long as the Unicode string contains only ASCII characters.
The result of calling RemoteTargetConnection.send_packet is a bytes
object containing the reply that came from the remote.
