We already have one set of property APIs in some sense.  qdev properties
*are* QOM properties; you visit them with object_property_foreach and so on.

The extensions that qdev adds, and are exclusive to qdev properties, are
the following:

- defining properties via DEFINE_PROPERTY_* (qdev_property_add_static etc.)

- defining default values with -global (global_props and a handful of
functions that use it).

- providing alternative human-readable formatting for info qtree
(qdev_property_add_legacy)
