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...

sysbus: apic: ioapic: convert to QEMU Object Model

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

hw/sysbus: Add sysbus_mmio_get_region()

Add a sysbus_mmio_get_region() which allows users of sysbus
devices to turn a (SysBusDevice*, mmioidx) tuple into a
MemoryRegion*. This enables some useful simplifications of
devices which pass through another device's mmio region...

sysbus: remove sysbus_init_mmio_cb()

This problem with this function is that it is not reversible - it is
impossible to know where things are registered and unregister them
exactly. As there are no more users, we can remove it.

sysbus: add a variant of sysbus_init_mmio_cb with an unmap callback

sysbus_init_mmio_cb() uses the destructive IO_MEM_UNASSIGNED to remove a
region. Provide an alternative that calls an unmap callback, so the removal
may be done non-destructively.

Revert "Get rid of _t suffix"

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...

qdev: add return value to init() callbacks.

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....
