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.

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 two devices at once because PIC subclasses ISA and converting
subclasses independently is extremely hard.

We need to initialize legacy_address_space during ISA VGA setup so that
the chain-4 alias can be registered properly.

Instead, use the bus accessors, or get the address space directly
from the board constructor.

Convert all vga memory to the memory API. Note we need to fall back to
get_system_memory(), since the various buses don't pass the vga window
as a memory region.
We no longer need to sync the dirty bitmap of the cirrus mapped memory
banks, since the memory API takes care of that for us.

When available, we'd like to be able to access the DeviceState
when registering a savevm. For buses with a get_dev_path()
function, this will allow us to create more unique savevm
id strings.

Apparently, VBE maps the VGA vram to a fixed physical location. KVM requires
that all mappings of the VGA vram have dirty tracking enabled on them. Any
access to the VGA vram through the VBE mapping currently fails to result in
dirty page tracking updates causing a black screen.
This is the true root cause of VMware VGA not working correctly under KVM and
likely also an issue with some of the std-vga black screen issues too.
Cirrus does not enable VBE so it would not be a problem when using Cirrus.
