qdev: Convert busses to QEMU Object Model
This is far less interesting than it sounds. We simply add an Object to eachBusState and then register the types appropriately. Most of the interestingrefactoring will follow in the next patches.
Since we're changing fundamental type names (BusInfo -> BusClass), it all needs...
qbus: Make child devices links
Make qbus children show up as link<> properties. There is no stableaddressing for qbus children so we use an unstable naming convention.
This is okay in QOM though because the composition name is expected tobe what's stable....
qdev: Move bus properties to a separate global
Simple code movement in order to simplify future refactoring.

qdev: Move bus properties to abstract superclasses
In qdev, each bus in practice identified an abstract superclass, butthis was mostly hidden. In QOM, instead, these abstract classes areexplicit so we can move bus properties there.
All bus property walks are removed, and all device property walks...
msi: Invoke msi/msix_reset from PCI core
There is no point in pushing this burden to the devices, they tend toforget to call them (like intel-hda, ahci, xhci did). Instead, resetfunctions are now called from pci_device_reset. They do nothing ifMSI/MSI-X is not in use....
msi: Invoke msi/msix_write_config from PCI core
Also this functions is better invoked by the core than by each and everydevice. This allows to drop the config_write callbacks from ich andintel-hda.

intel-hda: Fix reset of MSI function

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 wherenecessary and don't put a semicolon after the closing brace....
qdev: register all types natively through QEMU Object Model
This was done in a mostly automated fashion. I did it in three steps and thenrebased it into a single step which avoids repeatedly touching every file inthe tree.
The first step was a sed-based addition of the parent type to the subclass...
qdev: kill off DeviceInfo
It is no longer used in the tree since everything is done natively throughQEMU Object Model.

pci: convert to QEMU Object Model
hda-codec: convert to QEMU Object Model
qdev: use a wrapper to access reset and promote reset to a class method
qdev: don't access name through info
We already have a QOM interface for this so let's use it.
qdev: move qdev->info to class
Right now, DeviceInfo acts as the class for qdev. In order to switch to aproper ObjectClass derivative, we need to ween all of the callers off ofinteracting directly with the info pointer.
intel-hda: fix stream search
commit ba43d28916c4f51c19bd7366089155ce81bee058 introduces a bug:The stream-not-found case doesn't error out any more, instead thecode silently uses the first stream. Fix it.

qdev: switch children device list to QTAILQ
SCSI buses will need to read the children list first-to-last. Thisrequires using a QTAILQ, because hell breaks loose if you just tryinserting at the tail (thus reversing the order of all existingvisits from last-to-first to first-to-tail)....

Add endianness as io mem parameter
As stated before, devices can be little, big or native endian. Thetarget endianness is not of their concern, so we need to push thingsdown a level.
