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...

Currently creating a memory region automatically registers it forlive migration. This differs from other state (which is enumeratedin a VMStateDescription structure) and ties the live migration codeinto the memory core....
ivshmem: fix PCI BAR2 registration during initialization
Ivshmem cannot work, and the command lspci cannot show ivshmem BAR2 in the guest.As for pci_register_bar(), parameter MemoryRegion should be s->bar instead of s->ivshmem.

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.
This patch adds a parameter to cpu_register_io_memory that allows adevice to choose its endianness. For now, all devices simply choose...
