Make it clear that no BUS() macro is needed in the callers (in fact it
wouldn't work because the object has not been initialized yet with the
right class).

Introduce the QOM realizefn suggested by Anthony.
Detailed documentation is supplied in the qdev header.
For now this implements a default DeviceClass::realize callback that
just wraps DeviceClass::init, which it deprecates.
Once all devices have been converted to DeviceClass::realize,
DeviceClass::init is to be removed.

Whether the device was initialized or not is QOM-level information and
currently unused. Drop it from device. This leaves the boolean state of
whether or not DeviceClass::init was called or not, a.k.a. "realized".

Instead of keeping all those struct typedefs in qemu-common.h, move it
to a header that can be safely included by other headers, containing
only the struct typedefs and not pulling in other dependencies.
Also, move some of the qdev-core.h typedefs to the new file, too, so
other headers don't need to include qdev-core.h only because of
DeviceState and other typedefs.
This will help us remove qemu-common.h dependencies from some headers
later.

Header file dependency is a frickin' nightmare right now. cpu.h tends
to get included in our 'include everything' header files but qdev also
needs to include those headers mainly for qdev-properties since it knows
about CharDriverState and friends.
We can solve this for now by splitting out qdev.h along the same lines
that we previously split the C file. Then cpu.h just needs to include
qdev-core.h.
hw/qdev.h is split into following new headers:
hw/qdev-core.h
hw/qdev-properties.h
hw/qdev-monitor.h

[ehabkost: re-add DEFINE_PROP_PCI_HOST_DEVADDR, that was removed on the
original patch (by mistake, I guess)]
[ehabkost: kill qdev_prop_set_vlan() declaration]
[ehabkost: moved get_fw_dev_path() comment to the original location
(I don't know why it was moved)]
[ehabkost: removed qdev_exists() declaration]
[ehabkost: keep using 'QemuOpts' instead of 'struct QemuOpts', as
qdev-core.h includes qemu-option.h]
