3b50e311b4 qom: Add class_base_init
The class_base_init TypeInfo callback was present in one of the early
QOM versions but removed (on my request...) before committing.  We
will need it soon, add it.

dd83b06ae6 qom: Introduce CPU class
Reintroduce CPUState as QOM object: It's abstract and derived directly
from TYPE_OBJECT for compatibility with the user emulators.
The identifier CPUState avoids conflicts between CPU() and the struct.

Introduce $(qom-twice-y) to build it separately for system and for user
emulators.

Prepare a virtual reset method, (re)introduce cpu_reset() as wrapper.

Replace device_init() with generalized type_init().

Also, type_init() is a function, so add preceding blank line where
necessary and don't put a semicolon after the closing brace.

Move the creation of QmpInputVisitor and QmpOutputVisitor from qmp.c
to qom/object.c, since it's the only practical way to access object
properties.

Keep this isolated such that it's easy to remove.  At some point, we need
to remove all usage of QObject in the tree and replace it with GVariant.

57c9fafe0f qom: move properties from qdev to object
This is mostly code movement although not entirely.  This makes properties part
of the Object base class which means that we can now start using Object in a

39bffca203 qdev: register all types natively through QEMU Object Model
This was done in a mostly automated fashion.  I did it in three steps and then
rebased it into a single step which avoids repeatedly touching every file in
the tree.

The first step was a sed-based addition of the parent type to the subclass
registration functions.

The second step was another sed-based removal of subclass registration functions
while also adding virtual functions from the base class into a class_init
function as appropriate.

Finally, a python script was used to convert the DeviceInfo structures and
qdev_register_subclass functions to TypeInfo structures, class_init functions,
and type_register_static calls.

We are almost fully converted to QOM after this commit.
