Subject: [PATCH 16/16] qemu: capabilities: Enable detection of
QEMU_CAPS_OBJECT_QAPIFIED
Base the detection on the presence of the 'secret' qom-type entry, which
isn't conditionally compiled in qemu.
All caps-based test now switch to using JSON for -object.

Subject: [PATCH 10/16] qemu: capabilities: Introduce QEMU_CAPS_OBJECT_QAPIFIED
Starting from qemu-6.0 the parameters of -object/object-add are formally
described by the QAPI schema. Additionally this changes the nesting of
the properties as the 'props' nested object will be flattened to the
parent.
We'll need to detect whether qemu switched to this new approach to
generate the objects with proper nesting and also allow testing.

Subject: [PATCH 14/16] qemu: command: Use JSON for QAPIfied -object directly
Skip the lossy conversion to legacy commandline arguments by using the
JSON props directly when -object is QAPIfied. This avoids issues with
conversion of bitmaps and also allows validation of the generated JSON
against the QMP schema in the tests.
Since the new approach is triggered by a qemu capability the code
from 'virQEMUBuildObjectCommandlineFromJSON' in util/virqemu.c was moved
to 'qemuBuildObjectCommandlineFromJSON' in qemu/qemu_command.c which has
the virQEMUCaps type.
Some functions needed to be modified to propagate qemuCaps.

Subject: [PATCH 11/16] qemu: monitor: Make wrapping of 'props' of 'object-add'
optional
Construct the JSON object which is used for object-add without the
'props' wrapper and add the wrapper only in the monitor code.
This simplifies the JSON->commandline generator in the first place and
also prepares for upcoming qemu where 'props' will be removed.

The callers of qemuMonitorAddObject rely on the fact that @alias is
filled only when the object is added successfully. This is documented
but the code didn't behave like that.

Remove freeing/clearing of @props as the function doesn't guarantee that
it happens on success, rename the variable hodling copy of the alias and
use g_autofree to automatically free it and remove the cleanup label as
well as 'ret' variable.

There's just one caller left. Since qemuBuildMemoryBackendProps is too
complex to be modified for now, just move the adding of 'id' and 'qom'
type directly into the function.

Subject: [PATCH 03/16] :qemuMonitorJSONMakeCommandInternal: Clear @arguments
when stolen
All callers of qemuMonitorJSONMakeCommandInternal will benefit from
making @arguments a double pointer and passing it to
virJSONValueObjectCreate directly which will clear it if it steals the
value.
