Add explicit validation for QAPI documentation formatting rules:
1. Lines must not exceed 70 columns in width (including '# ' prefix)
2. Sentences must be separated by two spaces
Example sections and literal :: blocks (seldom case) are excluded, we
don't require them to be <= 70, that would be too restrictive. Anyway,
they share common 80-columns recommendations (not requirements).
Add two simple tests, illustrating the change.

The detection of example and literal blocks isn't quite correct, but
it works well enough, and we can improve on top.

qmp_marshal_output_T() is only ever called by qmp_marshal_C() for a
command C that returns type T.
We've always generated it as a static function on demand, i.e. when we
generate a call.
Since we split up monolithic generated code into modules (commit
252dc3105f "qapi: Generate separate .h, .c for each module"), we do
this per module. As noted in the commit message, this can result in
identical (static) qmp_marshal_output_T() in several modules. Was
deemed not worth avoiding.
A bit later, we added 'if' conditionals to the schema language (merge
commit 5dafaf4fbc).
When a conditional definition uses a type, then its condition must
imply the type's condition. We made this the user's responsibility.
Hasn't been an issue in practice.
However, the sharing of qmp_marshal_output_T() among commands
complicates matters. To avoid both undefined function errors and
unused function warnings, qmp_marshal_output_T() must be defined
exactly when it's used. It is used when any of the qmp_marshal_C()
calling it is defined, i.e. when any C's condition holds.
The generator uses T's condition instead. To avoid both error and
warning, T's condition must be the conjunction of all C's conditions.
Unfortunately, this can be impossible:
* Conditional command returning a builtin type
A builtin type cannot be conditional. This is noted in a FIXME
comment.
* Commands in multiple modules where the conjunction differs between
modules
An instance of this came up recently. we have unconditional
commands returning HumanReadableText. If we add a conditional one
to a module that does not have unconditional ones, compilation fails
with "defined but not used". If we make HumanReadableText
conditional to fix this module, we break the others.
Instead of complicating the code to compute the conjunction, simplify
it: generate the output marshaling code right into qmp_marshal_C().
This duplicates it when multiple commands return the same type. The
impact on code size is negligible: qemu-system-x86_64's text segment
grows by 1448 bytes.

[Commit message typos fixed]
The argparse.FileType() type has been deprecated in the latest argparse
version (e.g. the one from Fedora 43), now causing the test_bad_vmstate
functional test to fail since there are unexpected strings in the output.
Change the script to use pathlib.Path instead to fix the test_bad_vmstate
test and to be prepared for the future when the deprecated FileType gets
removed completely.

When the QMP library was updated to match the standalone repository in

All the functions are about "-audio model=" handling, a simpler
way to setup audio. Rename functions/variables to reflect this better.
audio_register_model_with_cb() dropped "pci" from the name, since it
will be generalized next.
deprecated_register_soundhw() was actually not a function to be
removed since it's used for "-audio model=" aliasing.

While working out what hoops to jump through to get a full set of
aarch32 packages installed on the aarch64 runner it was pointed out 32
bit host support is deprecated. As the extra packages where needed for
system emulation (marked deprecated since 8.0!) there didn't seem much
point keeping this in.
While the full expunging of 32 bit host support will probably be done
for 11.0 we can at least reduce the CI burden a bit now.

The download cache of the functional tests is currently only growing.
But sometimes tests get removed or changed to use different assets,
thus we should clean up the stale old assets after a while when they
are not in use anymore. So add a script that looks at the time stamps
of the assets and removes them if they haven't been touched for more
than half of a year. Since there might also be some assets around that
have been added to the cache before we added the time stamp files,
assume a default time stamp that is close to the creation date of this
patch, so that we don't delete these files too early (so we still have
all assets around in case we have to bisect an issue in the recent past
of QEMU).

The syslog backend needs the syslog function from libc and the LOG_INFO enum
value; they are re-exported as "::trace::syslog" and "::trace::LOG_INFO"
so that device crates do not all have to add the libc dependency, but
otherwise there is nothing special.

Generating .rs files makes it possible to support tracing in rust.
This support comprises a new format, and common code that converts
the C expressions in trace-events to Rust. In particular, types
need to be converted, and PRI macros expanded.
As of this commit no backend generates Rust code, but it is already
possible to use tracetool to generate Rust sources; they are not
functional but they compile and contain tracepoint functions.
[Move Rust argument conversion from Event to Arguments; string
support. - Paolo]

Use CHECK_TRACE_EVENT_GET_STATE in log, syslog, dtrace and simple
backend, so that the "if (trace_event_get_state)" is created from common
code and unified when multiple backends are active.
When a single backend is active there is no code change (except
for the log backend, as shown in tests/tracetool/log.h), but the
code in the backends is simpler.

Add a new attribute CHECK_TRACE_EVENT_GET_STATE to the backends.
When present and True, the code generated by the generate function
is wrapped in a conditional that checks whether the event is enabled;
this removes the need for repeating the same conditional in multiple
backends.

try_import returns a tuple of a boolean and the requested module or attribute.
exists() functions return tracetool.try_import("tracetool.format." + name)[1]
but they should return the boolean value instead.
