even though their name might be the same as a device's (e.g.

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.

object: sure up reference counting
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.

qom: add new command to search for types
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.

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.

When calling wait4 or waitpid with a status pointer and WNOHANG, the

if (status)

return the guest's initialized status variable instead of our own uninitialized.
