[CCing ML] This series aggressively refactors the PC machine initialization to be more modelled and less ad-hoc. The highlights of this series are:
1) Things like -m and -bios-name are now device model properties 2) The i440fx and piix3 are now modelled in a thorough fashion 3) Most of the chipset features of the piix3 are modelled through composition 4) i440fx_init is trivialized to creating devices and setting properties 5) convert MemoryRegion to QOM 6) convert PCI host bridge to QOM The point (4) is the most important one. As we refactor in this fashion, we should quickly get to the point where machine->init disappears completely in favor of just creating a handful of devices. The two stage initialization of QOM is important here. instance_init() is when composed devices are created which means that after you've created a device, all of its children are visible in the device model. This lets you set properties of the parent and its children. realize() (which is still called DeviceState::init today) will be called right before the guest starts up for the first time.
