This is far less interesting than it sounds. We simply add an Object to each
BusState and then register the types appropriately. Most of the interesting
refactoring will follow in the next patches.
Since we're changing fundamental type names (BusInfo -> BusClass), it all needs
to convert at once. Fortunately, not a lot of code is affected.

This makes it easier to remove it from BusInfo.

In qdev, each bus in practice identified an abstract superclass, but
this was mostly hidden. In QOM, instead, these abstract classes are
explicit so we can move bus properties there.
All bus property walks are removed, and all device property walks
are changed to look along the class hierarchy instead.
We would have duplicates if class A defines some properties and its
subclass B does not define any, because class_b->props will be
left equal to class_a->props.
The solution here is to reintroduce the class_base_init TypeInfo
callback, that was present in one of the early QOM versions but
removed (on my request...) before committing.
This breaks global bus properties, an obscure feature when used
with the command-line which is actually useful and used when used by
backwards-compatible machine types. So this patch also adjusts the
global bus properties in hw/pc_piix.c to refer to the abstract class.
Globals and other properties must be modified in the same patch to
avoid complications related to initialization ordering.

... to make vmstate id string truely unique with multiple host
controllers, i.e. move from "1/usb-ptr" to "0000:00:01.3/1/usb-ptr"
(usb tabled connected to piix3 uhci).
This obviously breaks migration. To handle this the usb bus
property "full-path" is added. When setting this to false old
behavior is maintained. This way current qemu will be compatible
with old versions when started using '-M pc-$oldversion'.

Reorganize usb source files. Create a new hw/usb/ directory and move
all usb source code to that place. Also make filenames a bit more
descriptive. Host adapters are prefixed with "hch-" now, usb device
emulations are prefixed with "dev-". Fixup paths Makefile and include
paths to make it compile. No code changes.
