This allows to restrict partial matches to objects of the expected
type. It will let people use bare names to reference drives
even though their name might be the same as a device's (e.g.
-drive id=hd0,if=none,... -device ...,drive=hd0,id=hd0).
As a useful byproduct, this fixes a problem with links of interface
type. When a link property's type is an interface, the code expects
the implementation object (not the parent object) to be stored in the
variable. The parent object does not contain the right vtable.

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.

The interface loop can be performed only on the parent object. It
does not need to be done on each interface. Similarly, we can
simplify the code by switching early from the implementation
object to the parent object.

Indeed, compilation failed for w32, so the bridge code is now
conditional. Hosts which don't support it can simply remove the

Now we have the following behavior:
1) object_new() returns an object with ref = 1
2) object_initialize() does not increase the reference count (ref may be 0).
3) object_deref() will finalize the object when ref = 0. it does not free the
memory associated with the object.
4) both link and child properties correctly set the reference count.
The expected usage is the following:
1) child devices should generally be created via object_initialize() using
memory from the parent device. Adding the object as a child property will
take ownership of the object and tie the child's life cycle to the parent.
2) If a child device is created via qdev_create() or some other form of
object_new(), there must be an object_delete() call in the parent device's
finalize function.

Links had limited utility before as they only allowed a concrete type to be
specified. Now we can support abstract types and interfaces which means it's
now possible to have a link<PCIDevice>.

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

This adds a command that allows searching for types that implement a property.
This allows you to do things like search for all available PCIDevices. In the
future, we'll also have a standard interface for things with a BlockDriverState
property that a PCIDevice could implement.
This will enable search queries like, "any type that implements the BlockDevice
interface" which would allow management tools to present available block devices
without having to hard code device names. Since an object can implement
multiple interfaces, one device could act both as a BlockDevice and a
NetworkDevice.

Limit them to the device_add functionality. Device aliases were a hack based
on the fact that virtio was modeled the wrong way. The mechanism for aliasing
is very limited in that only one alias can exist for any device.
We have to support it for the purposes of compatibility but we only need to
support it in device_add so restrict it to that piece of code.

- Use a table for aliases (Paolo)
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.
