Frees the identifier cpu_reset for QOM CPUs (manual rename).
Don't hide the parameter type behind explicit casts, use static
functions with strongly typed argument to indirect.

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 where
necessary and don't put a semicolon after the closing brace.

This was done in a mostly automated fashion. I did it in three steps and then
rebased it into a single step which avoids repeatedly touching every file in
the tree.
The first step was a sed-based addition of the parent type to the subclass
registration functions.
The second step was another sed-based removal of subclass registration functions
while also adding virtual functions from the base class into a class_init
function as appropriate.
Finally, a python script was used to convert the DeviceInfo structures and
qdev_register_subclass functions to TypeInfo structures, class_init functions,
and type_register_static calls.
We are almost fully converted to QOM after this commit.

This converts three devices because apic and ioapic are subclasses of sysbus.
Converting subclasses independently of their base class is prohibitively hard.

Currently creating a memory region automatically registers it for
live migration. This differs from other state (which is enumerated
in a VMStateDescription structure) and ties the live migration code
into the memory core.
Decouple the two by introducing a separate API, vmstate_register_ram(),
for registering a RAM block for migration. Currently the same
implementation is reused, but later it can be moved into a separate list,
and registrations can be moved to VMStateDescription blocks.

As stated before, devices can be little, big or native endian. The
target endianness is not of their concern, so we need to push things
down a level.
This patch adds a parameter to cpu_register_io_memory that allows a
device to choose its endianness. For now, all devices simply choose
native endian, because that's the same behavior as before.

These will be used to generate unique id strings for ramblocks. The name
field is required, the device pointer is optional as most callers don't
have a device. When there's no device or the device isn't a child of
a bus implementing BusInfo.get_dev_path, the name should be unique for
the platform.

Move ARMv7-M PC/SP initialization to the CPU reset routine. Add a board
reset routine to call this. Also load values directly from ROM as
images have not been copied yet.
Avoid clearing the NVIC pointer on cpu reset.

A few machines need to translate the ELF header addresses into physical
addresses. Currently the only possibility is to add a value to the
addresses.
This patch replaces the addend argument by and a translation function
and an opaque passed to the function. A NULL function does not translate
the address.
The patch also convert all machines that have an addend, simplify the
PowerPC kernel loading and fix the MIPS kernel loading using this new
feature. Other machines may benefit from this feature.

Like qdev_init(), but terminate program via hw_error() instead of
returning an error value.
Use it instead of qdev_init() where terminating the program on failure
is okay, either because it's during machine construction, or because
we know that failure can't happen.
Because relying in the latter is somewhat unclean, and the former is
not always obvious, it would be nice to go back to qdev_init() in the
not-so-obvious cases, only with proper error handling. I'm leaving
that for another day, because it involves making sure that error
values are properly checked by all callers.

In the very least, a change like this requires discussion on the list.
The naming convention is goofy and it causes a massive merge problem. Something
like this _must_ be presented on the list first so people can provide input
and cope with it.

Callers must pass ELF machine, byte swapping and symbol LSB clearing
information to ELF loader. A.out loader needs page size information, pass
that too as a parameter.
Extract prototypes to a separate file. Move loader.[ch] and elf_ops.h under hw.
Adjust callers. Also use target_phys_addr_t instead of target_ulong for
addresses: loader addresses aren't virtual.

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 init
callbacks can't signal failure because the init() callback has no
return value. This patch fixes it.
We have already one case in-tree where this is needed:
Try -device virtio-blk-pci (without drive= specified) and watch qemu
segfault. This patch fixes it.
With usb+scsi being converted to qdev we'll get more devices where the
init callback can fail for various reasons.

This patch is a major overhaul of the device properties. The properties
are saved directly in the device state struct now, the linked list of
property values is gone.
Advantages:
* We don't have to maintain the list with the property values.
* The value in the property list and the value actually used by
the device can't go out of sync any more (used to happen for
the pci.devfn == -1 case) because there is only one place where
the value is stored.
* A record describing the property is required now, you can't set
random properties any more.
There are bus-specific and device-specific properties. The former
should be used for properties common to all bus drivers. Typical
use case is bus addressing, i.e. pci.devfn and i2c.address.
Properties have a PropertyInfo struct attached with name, size and
function pointers to parse and print properties. A few common property
types have PropertyInfos defined in qdev-properties.c. Drivers are free
to implement their own very special property parsers if needed.
Properties can have default values. If unset they are zero-filled.
