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: 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: 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.

qom: Unify type registration

Replace device_init() with generalized type_init().

While at it, unify naming convention: type_init([$prefix_]register_types)
Also, type_init() is a function, so add preceding blank line where
necessary and don't put a semicolon after the closing brace....

qom: use object_resolve_path_type for links

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)....

qom: add property get/set wrappers for links

These can set a link to any object, as long as it is included in
the composition tree.
