qom: Refine container_get() to allow using a custom root

Specify the root to search from as argument. This avoids hardcoding
"/machine" in some places and makes it more flexible.

qom: add container_get

This is QOM "mkdir -p". It is useful when referring to
container objects such as "/machine".

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...

qom/object.c: rename type_class_init() to type_initialize()

Function name type_class_init() gave us a wrong impression of separation
of type's "class" and "object" entities initialization. Name type_initialize()
is more appropriate for type_class_init() function (considering what operations...

qom: Introduce object_class_get_list()

qom: if @instance_size==0, assign size of object to parent object size

QOM documentation states that for objects of type with @instance_size == 0 size
will be assigned to match parent object's size. But currently this feauture is
not implemented and qemu asserts during creation of object with zero instance_size....

qom: fix device hot-unplug

Property removal modifies the list, so it is not safe to continue
iteration. We know anyway that each object can have only one
parent (see object_property_add_child), so exit after finding
the requested object.

qom: In function object_set_link_property(), first call object_ref(), then object_unref().

In the old implementation, if the new value of the property links
to the same object, as the old value, that object is first unref-ed,
and then ref-ed. This leads to unintended deinitialization of that object....

qom: Fix object_initialize_with_type() assertion

Assert the object is at least sizeof(Object), not sizeof(ObjectClass).

qom: add generic string parsing/printing

Add generic property accessors that take a string and parse it
appropriately for the property type. All the magic here is done
by the new string-based visitors.
