Now that we can safely call QOBJECT() on QObject * as well as its
subtypes, we can have macros qobject_ref() / qobject_unref() that work
everywhere instead of having to use QINCREF() / QDECREF() for QObject
and qobject_incref() / qobject_decref() for its subtypes.
The replacement is mechanical, except I broke a long line, and added a
cast in monitor_qmp_cleanup_req_queue_locked(). Unlike
qobject_decref(), qobject_unref() doesn't accept void *.
Note that the new macros evaluate their argument exactly once, thus no
need to shout them.

All the use of QOM buys us here is the ability to destroy the thing
with object_unref(OBJECT(vmdesc)). Not worth the notational overhead.

Type QJSON lets you build JSON text. Its interface mirrors (a subset
of) abstract JSON syntax.
QAPI output visitors also produce JSON text. They assert their
preconditions and invariants, and therefore abort on incorrect use.
Contrastingly, QJSON does *not* detect incorrect use. It happily
produces invalid JSON then. This is what migration wants.
QJSON was designed for migration, and migration is its only user.
Move it to migration/ for proper coverage by MAINTAINERS, and to deter
accidental use outside migration.
[Pointed out by Eric: QJSON was added in commits 0457d07..b174257
