Move public headers to include/net, and leave private headers in net/.
Put the virtio headers in include/net/tap.h, removing the multiple copies
that existed. Leave include/net/tap.h as the interface for NICs, and
net/tap_int.h as the interface for OS-specific parts of the tap backend.

Store in the object the freeing function that will be used at deletion
time. This makes it possible to use object_delete on statically-allocated
(embedded) objects. Dually, it makes it possible to use object_unparent
and object_unref without leaking memory, when the lifetime of object
might extend until after the call to object_delete.

Add an ObjectClass method that is done at object_unparent time. It
should remove any backlinks to the object in the composition tree,
so that object_delete will be able to drop the last reference and
free the object.

The filename can be overridden but it expects a non-blocking source of entropy.
A typical invocation would be:
qemu -object rng-random,id=rng0 -device virtio-rng-pci,rng=rng0
This can also be used with /dev/urandom by using the command line:
qemu -object rng-random,filename=/dev/urandom,id=rng0 \
-device virtio-rng-pci,rng=rng0

The current implementation of Interfaces is poorly designed. Each interface
that an object implements ends up being an object that's tracked by the
implementing object. There's all sorts of gymnastics to deal with casting
between these objects.
But an interface shouldn't be associated with an Object. Interfaces are global
to a class. This patch moves all Interface knowledge to ObjectClass eliminating
the relationship between Object and Interfaces.
Interfaces are now abstract (as they should be) but this is okay. Interfaces
essentially act as additional parents for the classes and are treated as such.
With this new implementation, we should fully support derived interfaces
including reimplementing an inherited interface.
PC: Rebased against qom-next merge Jun-2012.
PC: Removed replication of cast logic for interfaces, i.e. there is only
one cast function - object_dynamic_cast() (and object_dynamic_cast_assert())

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.
