This was missed due to the fact that it's in the top level and it uses
'struct DeviceInfo' instead of 'DeviceInfo' for some strange reason.

Commit a7c36ee492 added code for a net
bridge and explicitly said that "this is very Linux centric".
Indeed, compilation failed for w32, so the bridge code is now
conditional. Hosts which don't support it can simply remove the
definition of CONFIG_NET_BRIDGE.

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
meaningful way outside of qdev.

This gets us closer to being able to object_new() a qdev type and have 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.

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
syscall can potentially not modify the status pointer input. Now if we
have guest code like:
int status = 0;
waitpid(pid, &status, WNOHANG);
if (status)
<breakage>
then we have to make sure that in case status did not change we actually
return the guest's initialized status variable instead of our own uninitialized.
We fail to do so today, as we proxy everything through an uninitialized status
variable which for me ended up always containing the last error code.
This patch fixes some test cases when building yast2-core in OBS for ARM.

While debugging some issues with QEMU_STRACE I stumbled over segmentation
faults that were pretty reproducible. Turns out we tried to treat a
normal return value as errno, resulting in an access over array boundaries
for the resolution.
Fix this by allowing failure to resolve invalid errnos into strings.
