[PATCH v2 04/12] qemu: capabilities: Introduce QEMU_CAPS_OBJECT_QAPIFIED

[Peter Krempa]

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.

The capability is based on the presence of the 'secret' object in the
'qom-type' enum.
