Since 39bffca203 (qdev: register all
types natively through QEMU Object Model), TypeInfo as used in
the common, non-iterative pattern is no longer amended with information
and should therefore be const.
Fix the documented QOM examples:
sed -i 's/static TypeInfo/static const TypeInfo/g' include/qom/object.h
Since frequently the wrong examples are being copied by contributors of
new devices, fix all types in the tree:
sed -i 's/^static TypeInfo/static const TypeInfo/g' */*.c
sed -i 's/^static TypeInfo/static const TypeInfo/g' */*/*.c
This also avoids to piggy-back these changes onto real functional
changes or other refactorings.

When -usb option is used, global varible usb_enabled is set.
And all the plaform will create one USB controller according
to this variable. In fact, global varibles make code hard
to read.
So this patch is to remove global variable usb_enabled and
add USB option in machine options. All the plaforms will get
USB option value from machine options.
USB option of machine options will be set either by:
* -usb
* -machine type=pseries,usb=on
Both these ways can work now. They both set USB option in
machine options. In the future, the first way will be removed.

The pxa2xx I2C controller can have its registers at an arbitrary offset
within the MemoryRegion it creates. We use this to create two controllers,
one which covers a region of size 0x10000 with registers starting at an
offset 0x1600 into that region, and a second one which covers a region
of size just 0x100 with the registers starting at the base of the region.
The implementation of this offsetting uses two qdev properties, "offset"
(which sets the offset which must be subtracted from the address to
get the offset into the actual register bank) and "size", which is the
size of the MemoryRegion. We were actually using "offset" for two
purposes: firstly the required one of handling the registers not being
at the base of the MemoryRegion, and secondly as a workaround for a
deficiency of QEMU. Until commit 5312bd8b3, if a MemoryRegion was mapped
at a non-page boundary, the address passed into the read and write
functions would be the offset from the start of the page, not the
offset from the start of the MemoryRegion. So when calculating the value
to set the "offset" qdev property we included a rounding to a page
boundary.
Following commit 5312bd8b3 MemoryRegion read/write functions are now
correctly passed the offset from the base of the region, and our
workaround now means we're subtracting too much from addresses, resulting
in warnings like "pxa2xx_i2c_read: Bad register 0xffffff90".
The fix for this is simply to remove the rounding to a page boundary;
this allows us to slightly simplify the expression since
base - (base & (~region_size)) == base & region_size
The qdev property "offset" itself must remain because it is still
performing its primary job of handling register banks not being at
the base of the MemoryRegion.

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.

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.
