Back in commit d9f059aa6c (qemu-img: Deprecate use of -b without -F),
we deprecated the ability to create a file with a backing image that
requires qemu to perform format probing. Qemu can still probe older
files for backwards compatibility, but it is time to finish off the
ability to create such images, due to the potential security risk they
present. Update a couple of iotests affected by the change.

It is not safe to pretend that emulated NVDIMM supports
persistence while backend actually failed to enable it
and used non-persistent mapping as fall back.
Instead of falling-back, QEMU should be more strict and
error out with clear message that it's not supported.
So if user asks for persistence (pmem=on), they should
store backing file on NVDIMM.

It's just a wrapper around the -display ...,window-close=off parameter,
and the name "no-quit" is rather confusing compared to "window-close"
(since there are still other means to quit the emulator), so we should
rather tell our users to use the "window-close" parameter instead.
While we're at it, update the documentation to state that
"-no-quit" is available for GTK, too, not only for SDL.

According to the QAPI schema, there is a "-" and not a "_" between
"window" and "close", and we're also talking about "window-close"
in the long parameter description in qemu-options.hx, so we should
make sure that we rather use the variant with the "-" by default
instead of only allowing the one with the "_" here. The old way
still stays enabled for compatibility, but we deprecate it, so that
we can switch to a QAPIfied parameter one day more easily.

When trying to remove the -usbdevice option, there were complaints that
"-usbdevice braille" is still a very useful shortcut for some people.
Thus we never remove this option. Since it's not such a big burden to
keep it around, and it's also convenient in the sense that you don't
have to worry to enable a host controller explicitly with this option,
we should remove it from he deprecation list again.
However, there is one exception: "-usbdevice audio" should go away, since
audio devices without "audiodev=..." parameter are also on the deprecation
list and you cannot use "-usbdevice audio" with "audiodev".

Supporting '0x20M' looks odd, particularly since we have a 'B' suffix
that is ambiguous for bytes, as well as a less-frequently-used 'E'
suffix for extremely large exibytes. In practice, people using hex
inputs are specifying values in bytes (and would have written
0x2000000, or possibly relied on default_suffix in the case of
qemu_strtosz_MiB), and the use of scaling suffixes makes the most
sense for inputs in decimal (where the user would write 32M). But
rather than outright dropping support for hex-with-suffix, let's
follow our deprecation policy. Sadly, since qemu_strtosz() does not
have an Err** parameter, and plumbing that in would be a much larger
task, we instead go with just directly emitting the deprecation
warning to stderr.

The "delay" option was a hack that was introduced to allow writing "nodelay".
We are adding a "nodelay" option to be used as "nodelay=on", so recommend it
instead of "delay".
This is quite ugly, but a proper deprecation of "delay"
cannot be done if QEMU starts suggesting it. Since it's the
only case I opted for this very much ad-hoc patch.

The userspace local APIC is basically untested and does not support many
features such as TSC deadline timer, x2APIC or PV spinlocks. On the
other hand, the PIT and IOAPIC are okay as they are not tied to
the processor and are tested with -M kernel-irqchip=split.
Therefore, deprecate the local APIC and, with it, limit
-M kernel-irqchip=off to the ISA PC machine type, which does not
have a local APIC at all.

The -enable-fips option was added a long time ago to prevent the use of
single DES when VNC when FIPS mode is enabled. It should never have been
added, because apps are supposed to unconditionally honour FIPS mode
based on the '/proc/sys/crypto/fips_enabled' file contents.
In addition there is more to achieving FIPS compliance than merely
blocking use of certain algorithms. Those algorithms which are used
need to perform self-tests at runtime.
QEMU's built-in cryptography provider has no support for self-tests,
and neither does the nettle library.
If QEMU is required to be used in a FIPS enabled host, then it must be
built with the libgcrypt library enabled, which will unconditionally
enforce FIPS compliance in any algorithm usage.
Thus there is no need to keep either the -enable-fips option in QEMU, or
QEMU's internal FIPS checking methods.

Options such as "server" or "nowait", that are commonly found in -chardev,
are sugar for "server=on" and "wait=off". This is quite surprising and
also does not have any notion of typing attached. It is even possible to
do "-device e1000,noid" and get a device with "id=off".
Deprecate it and print a warning when it is encountered. In general,
this short form for boolean options only seems to be in wide use for
