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.

When printing complaints with one of the execs from test-case
gdb.dwarf2/macro-source-path.exp, we run into:
...
$ gdb -q -batch \
-iex "set complaints 100" \
macro-source-path-clang14-dw4-absolute-cwd-32 \
-ex "p main"
During symbol reading: debug info runs off end of .debug_macro section \
[in module macro-source-path-clang14-dw4-absolute-cwd-32]
$1 = {int ()} 0x4004b7 <main>
...
and readelf complains more specifically:
...
Contents of the .debug_macro section:
Offset: 0
Version: 5
Offset size: 4
Offset into .debug_line: 0xe3
DW_MACRO_define - lineno : 0 macro : ONE 1
DW_MACRO_define_strp - lineno : 0 macro : THREE 3
DW_MACRO_start_file - lineno: 0 filenum: 1 filename: test.c
DW_MACRO_define - lineno : 1 macro : TWO 2
DW_MACRO_end_file
readelf: Error: .debug_macro section not zero terminated
...
Fix this by adding the missing terminator in Dwarf::_macro_unit.
Tested on x86_64-linux.

Add support for DW_MACRO_define_strp in dwarf assembly, and use it in
test-case gdb.dwarf2/macro-source-path.exp.
Tested on x86_64-linux.

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 changes some tests to use "require dwarf2_support".

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.

Using different ways of passing source file paths to compilers results n
different file and directory paths in the line header. For example:
- gcc foo.c
- gcc ./foo.c
- gcc ../cwd/foo.c
- gcc $PWD/foo.c
Because of this, GDB sometimes failed to look up macros. The previous
patch fixed that as much as possible. This patch adds the corresponding
tests.
Add both a DWARF assembler-based test and a regular test. The DWARF
assembled-based one tests some hard-coded debug info based on what I
have observed some specific versions of gcc and clang generate. We want
to make sure that GDB keeps handling all these cases correctly, even if
it's not always clear whether they are really valid DWARF. Also, they
will be tested no matter what the current target compiler is for a given
test run.
The regular test is compiled using the target compiler, so it may help
find bugs when testing against some other toolchains than what was used
to generate the DWARF assembler-based test.
For the DWARF assembler-based test, add to testsuite/lib/dwarf.exp the
necessary code to generate a DWARF5 .debug_macro section. The design of
the new procs is based on what was done for rnglists and loclists.
To test against a specific compiler one can use this command, for
example:
$ make check TESTS="gdb.base/macro-source-path.exp" RUNTESTFLAGS="CC_FOR_TARGET=clang --target_board unix/gdb:debug_flags=-gdwarf-5"
