Mapping object-add to the command line as is doesn't result in nice
syntax because of the nesting introduced with 'props'. This becomes
nicer and more consistent with device_add and netdev_add when we accept
properties for the object on the top level instead.
'props' is still accepted after this patch, but marked as deprecated.

It is not obvious what 'ignore' actually means for block jobs: It could
be continuing the job and returning success in the end despite the error
(no block job does this). It could also mean continuing and returning
failure in the end (this is what stream does). And it can mean retrying
the failed request later (this is what backup, commit and mirror do).
This (somewhat inconsistent) behaviour was introduced and described for
stream and mirror in commit 32c81a4a6e. backup and commit were

A handful of QAPI doc comments include lines like
"ppcemb: dropped in 3.1". The doc comment parser will just
put these into whatever the preceding section was; sometimes
that's "Notes", and sometimes it's some random other section,
as with "NetClientDriver" where the "'dump': dropped in 2.12"
line ends up in the "Since:" section.
This tends to render wrongly, more so in the upcoming rST
generator, but sometimes even in the Texinfo, as in the case
of QKeyCode:
ac_bookmarks
since 2.10 altgr, altgr_r: dropped in 2.10
Since commit 3264ffced3 (v4.2.0), we have a better place to tell
users about deprecated and deleted functionality --
qemu-deprecated.texi. These "dropped in" remarks all predate it, and
other feature drops of that vintage are not documented anywhere, so
moving these to qemu-deprecated.texi makes little sense. Drop them
instead.

doesn't recognize that markup and emits literal underscores.
Switch to *this* instead. Changes markup to strong emphasis with
Texinfo, commonly rendered as bold. With rST, it will go right back
to emphasis / italics.
rST also uses **this** for strong (commonly rendered bold) where
Texinfo uses *this*. We have one place in the doc comments
which uses strong/bold markup, in qapi/introspect.json:
Note: the QAPI schema is also used to help define *internal*

The current doc generation doesn't care much about indentation levels,
but we would like to switch to an rST format, and rST does care about
indentation.
Make the doc comments more strongly consistent about indentation
for multiline constructs like:
@arg: description line 1
description line 2
Returns: line one
line 2
so that there is always exactly one space after the colon, and
subsequent lines align with the first.
This commit is a purely whitespace change, and it does not alter the
generated .texi files (because the texi generation code strips away
all the extra whitespace). This does mean that we end up with some
over-length lines.
Note that when the documentation for an argument fits on a single
line like this:
@arg: one line only
then stray extra spaces after the ':' don't affect the rST output, so
I have not attempted to methodically fix them, though the preference
is a single space here too.

This patch adds this capability to blkdebug.
(Note that you cannot make blkdebug release or share permissions that it
needs to take or cannot share, because this might result in assertion

it will not take any permissions and share everything by default, so you
can then freely choose what permissions to take and share.)

1023 bytes. It is inconsistent if transient bitmaps do not have to
abide by the same limit, and it is unlikely that any existing client
even cares about using bitmap names this long. It's time to codify
that ALL bitmaps managed by qemu (whether persistent in qcow2 or not)
have a documented maximum length.

Add support for the query-cpu-model-expansion QMP command to Arm. We
do this selectively, only exposing CPU properties which represent
optional CPU features which the user may want to enable/disable.
Additionally we restrict the list of queryable cpu models to 'max',
'host', or the current type when KVM is in use. And, finally, we only
implement expansion type 'full', as Arm does not yet have a "base"
CPU type. More details and example queries are described in a new
document (docs/arm-cpu-features.rst).
Note, certainly more features may be added to the list of advertised
features, e.g. 'vfp' and 'neon'. The only requirement is that we can
detect invalid configurations and emit failures at QMP query time.
For 'vfp' and 'neon' this will require some refactoring to share a
validation function between the QMP query and the CPU realize
functions.

This patch adds a new migration state called wait-unplug. It is entered
after the SETUP state if failover devices are present. It will transition
into ACTIVE once all devices were succesfully unplugged from the guest.
So if a guest doesn't respond or takes long to honor the unplug request
the user will see the migration state 'wait-unplug'.
In the migration thread we query failover devices if they're are still
pending the guest unplug. When all are unplugged the migration
continues. If one device won't unplug migration will stay in wait_unplug
state.

When a command's 'data' is an object, its doc comment describes the
arguments defined there. When 'data' names a type, the doc comment
does not describe arguments. Instead, the doc generator inserts a
pointer to the named type.
An event's doc comment works the same.
We don't actually check doc comments for commands and events.
Instead, QAPISchema._def_command() forwards the doc comment to the
implicit argument type, where it gets checked. Works because the
check only cares for the implicit argument type's members.
Not only is this needlessly hard to understand, it actually falls
apart in two cases:
* When 'data' is empty, there is nothing to forward to, and the doc
comment remains unchecked. Demonstrated by test doc-bad-event-arg.
* When 'data' names a type, we can't forward, as the type has its own
doc comment. The command or event's doc comment remains unchecked.
Demonstrated by test doc-bad-boxed-command-arg.
The forwarding goes back to commit 069fb5b250 "qapi: Prepare for
requiring more complete documentation", put to use in commit
816a57cd6e "qapi: Fix detection of bogus member documentation". That
fix was incomplete.
To fix this, make QAPISchemaCommand and QAPISchemaEvent check doc
comments, and drop the forwarding of doc comments to implicit argument
types.

This patch adds support for blkreplay driver to the blockdev options.
Now blkreplay can be used with -blockdev command line option
in the following format:
-blockdev driver=blkreplay,image=file-node-name,node-name=replay-node-name
This option makes possible implementation of the better command
line support for record/replay invocations.

'savevm' was buggy as it considered all monitor-owned block device
nodes for snapshot. With the introduction of -blockdev, the common
usage made all nodes including protocol and backing file nodes be
monitor-owned and thus considered for snapshot.
This is a problem since the 'file' protocol nodes can't have internal
snapshots and it does not make sense to take snapshot of nodes
representing backing files.
This was fixed by commit 05f4aced65. Clients need to be able to
detect whether this fix is present.
Since savevm does not have an QMP alternative, add the feature for the
'human-monitor-command' backdoor which is used to call this command in
modern use.

This will allow us to disable mixeng when we use a decent backend.
Disabling mixeng have a few advantages:
* we no longer convert the audio output from one format to another, when
the underlying audio system would just convert it to a third format.
We no longer convert, only the underlying system, when needed.
* the underlying system probably has better resampling and sample format
converting methods anyway...
* we may support formats that the mixeng currently does not support (S24
or float samples, more than two channels)
* when using an audio server (like pulseaudio) different sound card
outputs will show up as separate streams, even if we use only one
backend
Disadvantages:
* audio capturing no longer works (wavcapture, and vnc audio extension)
* some backends only support a single playback stream or very picky
about the audio format. In this case we can't disable mixeng.
Originally thw two main use cases of the disabled option was: using
unsupported audio formats (5.1 and 7.1 audio) and having different
pulseaudio streams per audio frontend. Since we can have multiple
-audiodevs, the latter is not that important, so currently you only need
this option if you want to use 5.1 or 7.1 audio (implemented in a later
patch), otherwise it's probably better to stick to the old and tried
mixeng, since it's less picky about the backends.
The ideal solution would be to port as much as possible to gstreamer,
but this is currently out of scope:
