There's currently code in gdb that checks if an expression evaluates
to a type. In some spots this is done by comparing the opcode against
OP_TYPE, but other spots more correctly also compare with OP_TYPEOF
and OP_DECLTYPE.
This patch cleans up this area, replacing opcode-checking with a new
method on 'operation'.
Generally, checking the opcode should be considered deprecated,
although it's unfortunately difficult to get rid of opcodes entirely.
I also took advantage of this change to turn eval_op_type into a
method, removing a bit of indirection.

Most calls to lookup_minimal_symbol don't pass a value for sfile and
objf. Make these parameters optional (have a default value of
nullptr). And since passing a value to `objf` is much more common than
passing a value to `sfile`, swap the order so `objf` comes first, to
avoid having to pass a nullptr value to `sfile` when wanting to pass a
value to `objf`.

Currently an internal function handler has this prototype:
...
struct value *handler (struct gdbarch *gdbarch,
const struct language_defn *language,
void *cookie, int argc, struct value **argv);
...
Also allow an internal function with a handler with an additional
"enum noside noside" parameter:
...
struct value *handler (struct gdbarch *gdbarch,
const struct language_defn *language, void *cookie,
int argc, struct value **argv, enum noside noside);
...
In case such a handler is called with noside == EVAL_AVOID_SIDE_EFFECTS, it's
expected to return some value with the correct return type.
At least, provided it can do so without side effects, otherwise it should
throw an error.
No functional changes.

Currently it's not possible to call user-defined function call
operators, at least not without specifying operator() directly:
```
(gdb) l 1
1 struct S {
2 int operator() (int x) { return x + 5; }
3 };
4
5 int main () {
6 S s;
7
8 return s(23);
9 }
(gdb) p s(10)
Invalid data type for function to be called.
(gdb) p s.operator()(10)
$1 = 15
```
This now looks if an user-defined call operator is available when
trying to 'call' a struct value, and calls it instead, making this
possible:
```
(gdb) p s(10)
$1 = 15
```
The change in operation::evaluate_funcall is to make sure the type
fields are only used for function types, only they use them as the
argument types.

I noticed a spot in ada-lang.c where the return value of
value_as_address was cast to CORE_ADDR -- a no-op cast. I searched
and found another. This patch fixes both.

In Ada, sometimes the compiler must emit array bounds by referencing
an artificial variable that's created for this purpose. However, with
optimization enabled, these variables can be optimized away.
Currently this can result in displays like:
(gdb) print mumble
$1 = (warning: unable to get bounds of array, assuming null array
)
This patch changes this to report that the array is optimized-out,
instead, which is closer to the truth, and more generally useful. For
example, Python pretty-printers can now recognize this situation.
In order to accomplish this, I introduced a new PROP_OPTIMIZED_OUT
enumerator and changed one place to use it. Reusing the "unknown"
state wouldn't work properly, because in C it is normal for array
bounds to be unknown.

For Fortran pointers gfortran/ifx emits DW_TAG_pointer_types like
<2><17d>: Abbrev Number: 22 (DW_TAG_variable)
<180> DW_AT_name : (indirect string, offset: 0x1f1): fptr
<184> DW_AT_type : <0x214>
...
<1><219>: Abbrev Number: 27 (DW_TAG_array_type)
<21a> DW_AT_type : <0x10e>
<216> DW_AT_associated : ...
The 'pointer property' in Fortran is implicitly modeled by adding a
DW_AT_associated to the type of the variable (see also the
DW_AT_associated description in DWARF 5). A Fortran pointer is more
than an address and thus different from a C pointer. It is a
self contained type having additional fields such as, e.g., the rank of
its underlying array. This motivates the intended DWARF modeling of
Fortran pointers via the DW_AT_associated attribute.
This patch adds support for the sizeof intrinsic by simply dereferencing
pointer types when encountered during a sizeof evaluation.
The patch also adds a test for the sizeof intrinsic which was not tested
before.

This changes lookup_symbol and associated APIs to accept
domain_search_flags rather than a domain_enum.
Note that this introduces some new constants to Python and Guile. I
chose to break out the documentation patch for this, because the
internals here do not change until a later patch, and it seemed
simpler to patch the docs just once, rather than twice.

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.

Some functions related to the handling of registers in frames accept
"this frame", for which we want to read or write the register values,
while other functions accept "the next frame", which is the frame next
to that. The later is needed because we sometimes need to read register
values for a frame that does not exist yet (usually when trying to
unwind that frame-to-be).
value_of_register and value_of_register_lazy both take "this frame",
even if what they ultimately want internally is "the next frame". This
is annoying if you are in a spot that currently has "the next frame" and
need to call one of these functions (which happens later in this
series). You need to get the previous frame only for those functions to
get the next frame again. This is more manipulations, more chances of
mistake.
I propose to change these functions (and a few more functions in the
subsequent patches) to operate on "the next frame". Things become a bit
less awkward when all these functions agree on which frame they take.
So, in this patch, change value_of_register_lazy and value_of_register
to take "the next frame" instead of "this frame". This adds a lot of
get_next_frame_sentinel_okay, but if we convert the user registers API
to also use "the next frame" instead of "this frame", it will get simple
again.

Given that GDB now requires a C++17, replace all uses of
gdb::string_view with std::string_view.
This change has mostly been done automatically:
- gdb::string_view -> std::string_view
- #include "gdbsupport/gdb_string_view.h" -> #include <string_view>
One things which got brought up during review is that gdb::stging_view
does support being built from "nullptr" while std::sting_view does not.
Two places are manually adjusted to account for this difference:
gdb/tui/tui-io.c:tui_getc_1 and
gdbsupport/format.h:format_piece::format_piece.
The above automatic change transformed
"gdb::to_string (const gdb::string_view &)" into
"gdb::to_string (const std::string_view &)". The various direct users
of this function are now explicitly including
"gdbsupport/gdb_string_view.h". A later patch will remove the users of
gdb::to_string.
The implementation and tests of gdb::string_view are unchanged, they will
be removed in a following patch.

Since GDB now requires C++17, we don't need the internally maintained
gdb::optional implementation. This patch does the following replacing:
- gdb::optional -> std::optional
- gdb::in_place -> std::in_place
- #include "gdbsupport/gdb_optional.h" -> #include <optional>
This change has mostly been done automatically. One exception is
gdbsupport/thread-pool.* which did not use the gdb:: prefix as it
already lives in the gdb namespace.

binop_promote currently only handles integer sizes up to
builtin_long_long. However, this may not handle 128-bit types.
Simplify this code, unify the C and non-C (but not OpenCL, as I don't
know how to test this) cases, and handle 128-bit integers as well.
This still doesn't exactly follow C or C++ rules. This could be
implemented, but if so, I think it makes more sense as a C-specific
expression node.
