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.

C++17 makes the second parameter to static_assert optional, so we can
remove gdb_static_assert now.

This changes gdb to use the C++17 [[fallthrough]] attribute rather
than special comments.
This was mostly done by script, but I neglected a few spellings and so
also fixed it up by hand.
I suspect this fixes the bug mentioned below, by switching to a
standard approach that, presumably, clang supports.

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.

Remove get_current_regcache, inlining the call to get_thread_regcache in
callers. When possible, pass the right thread_info object known from
the local context. Otherwise, fall back to passing `inferior_thread ()`.
This makes the reference to global context bubble up one level, a small
step towards the long term goal of reducing the number of references to
global context (or rather, moving those references as close as possible
to the top of the call tree).
No behavior change expected.

This function is just a wrapper around the current inferior's gdbarch.
I find that having that wrapper just obscures where the arch is coming
from, and that it's often used as "I don't know which arch to use so
I'll use this magical target_gdbarch function that gets me an arch" when
the arch should in fact come from something in the context (a thread,
objfile, symbol, etc). I think that removing it and inlining
`current_inferior ()->arch ()` everywhere will make it a bit clearer
where that arch comes from and will trigger people into reflecting
whether this is the right place to get the arch or not.

Following the commit f818c32ba459 ("gdb/mi: fix ^running record with
multiple MI interpreters"), I thought it would make sense to make
current_token a field of mi_interp. This variable contains the token of
the currently handled MI command, like the 222 in:
222-exec-continue
I didn't find any bug related to that, it's just a "that seems nicer"
cleanup, since the current token is a fundamentally per-interp thing.
mi_execute_command needs a check similar to what we already have in
mi_cmd_gdb_exit: when invoked from Python's gdb.execute_mi, the current
interpreter is not an mi_interp. When using the Python gdb.execute_mi
function, there is no such concept of token, so we can just skip that.
There should be no user-visible change.

This commit fixes this by moving the thread exit printing to common
code instead, triggered from within delete_thread (or rather,
set_thread_exited).
There's one wrinkle, though. While most targest want to print:
[Thread ... exited]
the Windows target wants to print:
[Thread ... exited with code <exit_code>]
... and sometimes wants to suppress the notification for the main
thread. To address that, this commits adds a delete_thread_with_code
function, only used by that target (so far).
This fix was originally posted as part of a larger series:
https://inbox.sourceware.org/gdb-patches/20221212203101.1034916-1-pedro@palves.net/

Remove the static mi_parse::make functions, and instead use the
mi_parse constructor.
This is a partial revert of the commit:
commit fde3f93adb50c9937cd2e1c93561aea2fd167156
Date: Mon Mar 20 10:56:55 2023 -0600
Introduce "static constructor" for mi_parse
which introduced the mi_parse::make functions, though after discussion
on the list the reasons for seem to have been lost[1]. Given there
are no test regressions when moving back to using the constructors, I
propose we should do that for now.
There should be no user visible changes after this commit.

This commit extends the breakpoint mechanism to allow for inferior
specific breakpoints (but not watchpoints in this commit).
As GDB gains better support for multiple connections, and so for
running multiple (possibly unrelated) inferiors, then it is not hard
to imagine that a user might wish to create breakpoints that apply to
any thread in a single inferior. To achieve this currently, the user
would need to create a condition possibly making use of the $_inferior
convenience variable, which, though functional, isn't the most user
friendly.
This commit adds a new 'inferior' keyword that allows for the creation
of inferior specific breakpoints.
Inferior specific breakpoints are automatically deleted when the
associated inferior is removed from GDB, this is similar to how
thread-specific breakpoints are deleted when the associated thread is
deleted.
Watchpoints are already per-program-space, which in most cases mean
watchpoints are already inferior specific. There is a small window
where inferior-specific watchpoints might make sense, which is after a
vfork, when two processes are sharing the same address space.
However, I'm leaving that as an exercise for another day. For now,
attempting to use the inferior keyword with a watchpoint will give an
error, like this:
(gdb) watch a8 inferior 1
Cannot use 'inferior' keyword with watchpoints
A final note on the implementation: currently, inferior specific
breakpoints, like thread-specific breakpoints, are inserted into every
inferior, GDB then checks once the inferior stops if we are in the
correct thread or inferior, and resumes automatically if we stopped in
the wrong thread/inferior.
An obvious optimisation here is to only insert breakpoint locations
into the specific program space (which mostly means inferior) that
contains either the inferior or thread we are interested in. This
would reduce the number times GDB has to stop and then resume again in
a multi-inferior setup.
I have a series on the mailing list[1] that implements this
optimisation for thread-specific breakpoints. Once this series has
landed I'll update that series to also handle inferior specific
breakpoints in the same way. For now, inferior specific breakpoints
are just slightly less optimal, but this is no different to
thread-specific breakpoints in a multi-inferior debug session, so I
don't see this as a huge problem.

Simon noticed a crash that could be caused via new Python
gdb.execute_mi function. Looking into this, I found a few unchecked
casts to mi_interp, like:
- struct mi_interp *mi = (struct mi_interp *) command_interp ();
This patch replaces all such casts with safer variants.
For -gdb-exit and mi_load_progress, I chose to have the functions
simply not generate any output. It didn't seem useful to do so.
Some casts I eliminated by adding a parameter to a function. Then, in
mi_execute_command, I changed the code to use
gdb::checked_static_cast. This is appropriate because this particular
overload can only be called by the MI interpreter.
There does not seem to be a very good way to test -gdb-exit.
Regression tested on x86-64 Fedora 36.
