Done with this script:
cd hw

echo '\,^#.*include.*["<]'$i'[">], s,'$i',hw/&,'
done | sed -i -f - `find . -type f`
This is so that paths remain valid as files are moved.
Instead, files in hw/dataplane are referenced with the relative path.
We know they are not going to move to include/, and they are the only
include files that are in subdirectories _and_ move.

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.

Functions pci_vga_init() and pci_cirrus_vga_init() are declared
in pc.h. That prevents other platforms (e.g. sPAPR) to use them.
This patch is to create one new file vga-pci.h and move the
declarations to vga-pci.h, so that they can be shared by
all platforms. This patch also cleans up on all platforms.

Zap the global VGA_RAM_SIZE #define, make the vga ram size configurable
for standard vga and vmware vga. cirrus and qxl are left with a fixed
size (and private VGA_RAM_SIZE #define) for now.
qxl needs some non-trivial adjustments in the mode list handling deal
with a runtime-configurable size, which calls for a separate qxl patch.
cirrus emulates cards which have 2 MB (isa) and 4 MB (pci), so I guess
it would make sense to use these sizes. That change would break
migration though, so I left it fixed at 8 MB size. Making it
configurabls is pretty pointless for cirrus as we have to match real
hardware.

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.
