create struct for machine initialization arguments

This should help us to:
- More easily add or remove machine initialization arguments without
having to change every single machine init function;
- More easily make mechanical changes involving the machine init
functions in the future;
- Let machine initialization forward the init arguments to other
functions more easily.

This change was half-mechanical process: first the struct was added with
the local ram_size, boot_device, kernel_*, initrd_*, and cpu_model local
variable initialization to all functions. Then the compiler helped me
locate the local variables that are unused, so they could be removed.

We can't however replace the built-in IDE controller, as the one in

pc87312's IDE function gets disabled via the config property.

PReP emulation also gains a parallel port emulation this way.

qdev: add children before qdev_init

We want the composition tree to to be in order by the time we call
qdev_init, so that a single set of the toplevel realize property can
propagate all the way down the composition tree.

This is not the case so far. Unfortunately, this is incompatible
with calling qdev_init in the constructor wrappers for devices,
so for now we need to unattach some devices that are created through
those wrappers. This will be fixed by removing qdev_init and instead
setting the toplevel realize property after machine init.

qdev: register all types natively through QEMU Object Model

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.

The BIOS MemoryRegion is created with a fixed size of 1 MiB.

vectors are located at 0xfff00000 and the BIOS may want to use them.

It thereby no longer depends on the actual BIOS binary size.

vmstate, memory: decouple vmstate from memory API

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.
