For change, pause, resume, complete, dismiss and finalize actions
corresponding job- and block-job commands are almost equal. The
difference is in find_block_job_locked() vs find_job_locked()
functions. What's different?
1. find_block_job_locked() checks whether the found job is a block-job.
This is OK when moving to more generic API, no needs to document this
change.
2. find_block_job_locked() reports DeviceNotActive on failure, when
find_job_locked() reports GenericError. So, let's document this
difference in deprecated.txt. Still, for dismiss and finalize errors
are not documented at all, so be silent in deprecated.txt as well.

Commit 5b4beba124 ("RISC-V Spike Machines") added the Spike machine and
made it default for qemu-system-riscv32/64. It was the first RISC-V
machine added in QEMU so setting it as default was sensible.
Today we have 7 riscv64 and 6 riscv32 machines and having 'spike' as
default machine is not intuitive. For example, [1] is a bug that was
opened with the 'virt' board in mind, but given that the user didn't
pass a '-machine' option, the user was using 'spike' without knowing.
Being explicit in the command line is desirable when we have a handful
of boards available, so deprecate the default machine setting from
RISC-V.

The '-old-param' command line option is specific to Arm targets; it
is very briefly documented as "old param mode". What this option
actually does is change the behaviour when directly booting a guest
kernel, so that command line arguments are passed to the kernel using
the extremely old "param_struct" ABI, rather than the newer ATAGS or
even newer DTB mechanisms.
This support was added back in 2007 to support an old vendor kernel
on the akita/terrier board types:
https://mail.gnu.org/archive/html/qemu-devel/2007-07/msg00344.html
Even then, it was an out-of-date mechanism from the kernel's
point of view -- the kernel has had a comment since 2001 marking
it as deprecated. As of mid-2024, the kernel only retained
param_struct support for the RiscPC and Footbridge platforms:
https://lore.kernel.org/linux-arm-kernel/2831c5a6-cfbf-4fe0-b51c-0396e5b0aeb7@app.fastmail.com/

The pxa2xx CPUs are now only useful with user-mode emulation, because
we dropped all the machine types that used them in 9.2. (Technically
you could alse use "-cpu pxa270" with a board model like versatilepb
which doesn't sanity-check the CPU type, but that has never been a
supported config.)
To use them (or iwMMXt emulation) with QEMU user-mode you would need
to explicitly select them with the -cpu option or the QEMU_CPU
environment variable. A google search finds no examples of anybody
doing this in the last decade; I don't believe the GCC folks are
using QEMU to test their iwMMXt codegen either. In fact, GCC is in
the process of dropping support for iwMMXT entirely.
The iwMMXt emulation is thousands of lines of code in QEMU, and
is now the only bit of Arm insn decode which doesn't use decodetree.
We have no way to test or validate changes to it. This code is
just dead weight that is almost certainly not being used by anybody.
Mark it as deprecated.

Cope with the old version that is provided in Debian 12.
--size_t-is-usize is needed on bindgen <0.61.0, and it was removed in
bindgen 0.65.0, so check for it in meson.build.
--merge-extern-blocks was added in 0.61.0.
--formatter rustfmt was added in 0.65.0 and is the default, so remove it.
Apart from Debian 12 and Ubuntu 22.04, all other supported distros have

When the xlnx-zynqmp-pmu machine's CPU was added in commit 133d23b3ad
("xlnx-zynqmp-pmu: Add the CPU and memory"), its 'endianness' property
was set to %true, thus wired in little endianness.
Both machine are included in the big-endian system binary, while their
CPU is working in little-endian. Unlikely to work as it. Deprecate now

Per previous discussion [1,2], this patch deprecates query-migrationthreads
command.
To summarize, the major reason of the deprecation is due to no sensible way
to consume the API properly:
(1) The reported list of threads are incomplete (ignoring destination
threads and non-multifd threads).
(2) For CPU pinning, there's no way to properly pin the threads with
the API if the threads will start running right away after migration
threads can be queried, so the threads will always run on the default
cores for a short window.
(3) For VM debugging, one can use "-name $VM,debug-threads=on" instead,
which will provide proper names for all migration threads.

The ``-portrait`` and ``-rotate`` options were documented as only
working with the PXA LCD device, and all the machine types using
that display device were removed in 9.2.
These options were intended to simulate a mobile device being
rotated by the user, and had three effects:
* the display output was rotated by 90, 180 or 270 degrees
(implemented in the PXA display device models)
* the mouse/trackpad input was rotated the opposite way
(implemented in generic code)
* the machine model would signal to the guest about its
orientation
(implemented by e.g. the spitz machine model)
Of these three things, the input-rotation was coded without being
restricted to boards which supported the full set of device-rotation
handling, so in theory the options were usable on other machine
models with odd effects (rotating input but not display output). But
this was never intended or documented behaviour, so we can reasonably
drop these command line arguments without a formal deprecate-and-drop
cycle for them.
Remove the options, and their implementation and documentation.
Describe the removal in removed-features.rst.

The 'reconnect' option only allows to specify the time in seconds,
which is way too long for certain workflows.
We have a lightweight disk backend server, which takes about 20ms to
live update, but due to this limitation in QEMU, previously the guest
disk controller would hang for one second because it would take this
long for QEMU to reinitialize the socket connection.
Introduce a new option called 'reconnect-ms', which is the same as
'reconnect', except the value is treated as milliseconds. These are
mutually exclusive and specifying both results in an error.
'reconnect' is also deprecated by this commit to make it possible to
remove it in the future as to not keep two options that control the
same thing.

The zero-blocks capability was meant to be used along with the block
migration, which has been removed already in commit eef0bae3a7
("migration: Remove block migration").
Setting zero-blocks is currently a noop, but the outright removal of
the capability would cause and error in case some users are still
setting it. Put the capability through the deprecation process.

According to https://marc.info/?l=fedora-devel-list&m=171934833215726
the GlusterFS development effectively ended. Thus mark it as deprecated
in QEMU, so we can remove it in a future release if the project does
not gain momentum again.
