meson: define symbols for all available audio drivers
All drivers are now built by default if the corresponding libraries
are available, similar to how all other modules behave;
--audio-drv-list only governs the default choice of the audio driver.
Adjust the CONFIG_AUDIO_* preprocessor symbols so that they are
based on library availability rather than --audio-drv-list, so that
the tests and -audiodev help follow the new logic.

configure, meson: move audio driver detection to Meson
This brings a change that makes audio drivers more similar to all

--audio-drv-list only governs the default choice of the audio driver.
Meson options are added to disable the drivers, and the next patches
will fix the help messages and command line options, and especially
make the non-default drivers available via -audiodev.

The previous cpu_ldst.h functions did not have alignment info,
and so did not enforce it. Retain this by adding MO_UNALN to
the MemOp that we create in calling the new functions.

Commit 6287d827d4 "monitor: allow device_del to accept QOM paths"
extended find_device_state() to accept QOM paths in addition to qdev
IDs. This added a checked conversion to TYPE_DEVICE at the end, which
duplicates the check done for the qdev ID case earlier, except it sets
a *different* error: GenericError "ID is not a hotpluggable device"
when passed a QOM path, and DeviceNotFound "Device 'ID' not found"
when passed a qdev ID. Fortunately, the latter won't happen as long
as we add only devices to /machine/peripheral/.
Earlier, commit b6cc36abb2 "qdev: device_del: Search for to be
unplugged device in 'peripheral' container" rewrote the lookup by qdev
ID to use QOM instead of qdev_find_recursive(), so it can handle
buss-less devices. It does so by constructing an absolute QOM path.
Works, but object_resolve_path_component() is easier. Switching to it
also gets rid of the unclean duplication described above.
While there, avoid converting to TYPE_DEVICE twice, first to check
whether it's possible, and then for real.

python/qmp: clear events on get_events() call
All callers in the tree *already* clear the events after a call to
get_events(). Do it automatically instead and update callsites to remove
the manual clear call.
These semantics are quite a bit easier to emulate with async QMP, and
nobody appears to be abusing some emergent properties of what happens if
you decide not to clear them, so let's dial down to the dumber, simpler
thing.
Specifically: callers of clear() right after a call to get_events() are
more likely expressing their desire to not see any events they just
retrieved, whereas callers of clear_events() not in relation to a recent
call to pull_event/get_events are likely expressing their desire to
simply drop *all* pending events straight onto the floor. In the sync
world, this is safe enough; in the async world it's nearly impossible to
promise that nothing happens between getting and clearing the
events.
Making the retrieval also clear the queue is vastly simpler.

python/aqmp: Disable logging messages by default
AQMP is a library, and ideally it should not print error diagnostics
unless a user opts into seeing them. By default, Python will print all
WARNING, ERROR or CRITICAL messages to screen if no logging
configuration has been created by a client application.
In AQMP's case, ERROR logging statements are used to report additional
detail about runtime failures that will also eventually be reported to the
client library via an Exception, so these messages should not be
rendered by default.
(Why bother to have them at all, then? In async contexts, there may be
multiple Exceptions and we are only able to report one of them back to
the client application. It is not reasonably easy to predict ahead of
time if one or more of these Exceptions will be squelched. Therefore,
it's useful to log intermediate failures to help make sense of the
ultimate, resulting failure.)
Add a NullHandler that will suppress these messages until a client
application opts into logging via logging.basicConfig or similar. Note
that upon calling basicConfig(), this handler will *not* suppress these
messages from being displayed by the client's configuration.

python/aqmp: add send_fd_scm
Add an implementation for send_fd_scm to the async QMP implementation.
Like socket_scm_helper mentions, a non-empty payload is required for
QEMU to process the ancillary data. A space is most useful because it
does not disturb the parsing of subsequent JSON objects.
A note on "voiding the warranty":
Python 3.11 removes support for calling sendmsg directly from a
transport's socket. There is no other interface for doing this, our use
case is, I suspect, "quite unique".
As far as I can tell, this is safe to do -- send_fd_scm is a synchronous
function and we can be guaranteed that the async coroutines will *not* be
running when it is invoked. In testing, it works correctly.
I investigated quite thoroughly the possibility of creating my own
asyncio Transport (The class that ultimately manages the raw socket
object) so that I could manage the socket myself, but this is so wildly
invasive and unportable I scrapped the idea. It would involve a lot of
copy-pasting of various python utilities and classes just to re-create
the same infrastructure, and for extremely little benefit. Nah.
Just boldly void the warranty instead, while I try to follow up on

indexed array lookup.
However to get to this point we re-factor the code and remove the
second hand instruction boundary detection in favour of scanning the
