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.

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.

gdb/fortran: Move Fortran expression handling into f-lang.c
A bug was introduced that broke GDB's ability to perform debug dumps
of expressions containing function calls. For example this would no
longer work:
(gdb) set debug expression 1
(gdb) print call_me (&val)
Dump of expression @ 0x4eced60, before conversion to prefix form:
Language c, 12 elements, 16 bytes each.
Index Opcode Hex Value String Value
0 OP_VAR_VALUE 40 (...............
1 OP_M2_STRING 79862864 P...............
2 unknown opcode: 224 79862240 ................
3 OP_VAR_VALUE 40 (...............
4 OP_VAR_VALUE 40 (...............
5 OP_RUST_ARRAY 79861600 `...............
6 UNOP_PREDECREMENT 79861312 @...............
7 OP_VAR_VALUE 40 (...............
8 UNOP_ADDR 61 =...............
9 OP_FUNCALL 46 ................
10 BINOP_ADD 1 ................
11 OP_FUNCALL 46 ................
Dump of expression @ 0x4eced60, after conversion to prefix form:
Expression: `call_me (&main::val, VAL(Aborted (core dumped)
The situation was even worse for Fortran function calls, or array
indexes, which both make use of the same expression opcode.
The problem was that in a couple of places the index into the
expression array was handled incorrectly causing GDB to interpret
elements incorrectly. These issues are fixed in this commit.
There are already some tests to check GDB when 'set debug expression
1' is set, these can be found in gdb.*/debug-expr.exp. Unfortunately
the cases above were not covered.
In this commit I have cleaned up all of the debug-expr.exp files a
little, there was a helper function that had clearly been copied into
each file, this is now moved into lib/gdb.exp.
I've added a gdb.fortran/debug-expr.exp test file, and extended
gdb.base/debug-expr.exp to cover the function call case.
gdb/ChangeLog:
* expprint.c (print_subexp_funcall): Increment expression position
after reading argument count.
* f-lang.c (print_subexp_f): Skip over opcode before calling
common function.
(dump_subexp_body_f): Likewise.
gdb/testsuite/ChangeLog:
* gdb.base/debug-expr.c: Add extra function to allow for an
additional test.
* gdb.base/debug-expr.exp (test_debug_expr): Delete, replace calls
to this proc with gdb_test_debug_expr. Add an extra test.
* gdb.cp/debug-expr.exp (test_debug_expr): Delete, replace calls
to this proc with gdb_test_debug_expr, give the tests names
* gdb.dlang/debug-expr.exp (test_debug_expr): Delete, replace
calls to this proc with gdb_test_debug_expr, give the tests names
* gdb.fortran/debug-expr.exp: New file.
* gdb.fortran/debug-expr.f90: New file.
* lib/gdb.exp (gdb_test_debug_expr): New proc.
