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.

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.

While testing mixed-lang-stack I realized that valgrind actually
complained about a double free in the test.
All done

Reason for this is that in mixed-lang-stack.cpp in mixed_func_1f an
object "derived_type obj" goes on the stack which is then passed-by-value
(so copied) to mixed_func_1g. The default copy-ctor will be called but,
since derived_type contains a heap allocated string and the copy
constructor is not implemented it will only be able to shallow copy the
object. Right after each of the functions the object gets freed - on the
other hand the d'tor of derived_type actually is implemented and calls
free on the heap allocated string which leads to a double free. Instead
of obeying the rule of 3/5 I just got rid of all that since it does not
serve the test. The string is now just a const char* = ".." object
member.

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.

I noticed some files in the test-suite have GPLv2 notices.
Update these to GPLv3.

This commit adds a test that builds a mixed language stack, the stack
contains frames of Fortran, C, and C++. The test prints the backtrace
and explores the stack printing arguments of different types in frames
of different languages.
The core of the test is repeated with GDB's language set to auto,
fortran, c, and c++ in turn to ensure that GDB is happy to print
frames and frame arguments when the language is set to a value that
doesn't match the frame language.
This test currently passes, and there are no known bugs in this area.
The aim of this commit is simply to increase test coverage, as I don't
believe this functionality is currently tested.
