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...
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.

i2c: rename i2c_slave -> I2CSlave
i2c: smbus: convert to QEMU Object Model
This converts two types because smbus is implemented as a subclass of i2c. It'sextremely difficult to convert these two independently.
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)....

savevm: Add DeviceState param
When available, we'd like to be able to access the DeviceStatewhen registering a savevm. For buses with a get_dev_path()function, this will allow us to create more unique savevmid strings.

fix I2C slave addressing
With the recent device handling changes the I2C slave addressing codewas broken. With current code, if a slave with the correct address is
not found on the bus the last scanned slave on the bus will beaddressed. This is wrong. Please find attached a patch to fix it....
New qdev_init_nofail()
Like qdev_init(), but terminate program via hw_error() instead ofreturning an error value.
Use it instead of qdev_init() where terminating the program on failureis okay, either because it's during machine construction, or because...

Fix sys-queue.h conflict for good
Problem: Our file sys-queue.h is a copy of the BSD file, but there aresome additions and it's not entirely compatible. Because of that, there havebeen conflicts with system headers on BSD systems. Some hacks have beenintroduced in the commits 15cc9235840a22c289edbe064a9b3c19c5f49896,...
qdev: add return value to init() callbacks.
Sorry folks, but it has to be. One more of these invasive qdev patches.
We have a serious design bug in the qdev interface: device initcallbacks can't signal failure because the init() callback has noreturn value. This patch fixes it....

qdev: rework device properties.
This patch is a major overhaul of the device properties. The propertiesare saved directly in the device state struct now, the linked list ofproperty values is gone.
Advantages: * We don't have to maintain the list with the property values....
qdev: replace bus_type enum with bus_info struct.
BusInfo is filled with name and size (pretty much like I did forDeviceInfo as well). There is also a function pointer to printbus-specific device information to the monitor. sysbus is hookedup there, I've also added a print function for PCI....
qdev: move name+size into DeviceInfo (v2)
Rationale: move device information from code to data structures.
v2: Adapt the drivers missed in the first version.

Add common BusState
Implement and use a common device bus state. The main side-effect isthat creating a bus and attaching it to a parent device are no longerseparate operations. For legacy code we allow a NULL parent, but thatshould go away eventually....
