While I think generalizing the _code_ for static properties is obviously
a good idea, I am not sure about generalizing the interface for adding them.

The reason is that we already have a place for adding properties in
class_init, and having a second makes things "less local", so to speak.

What do you think about adding macros like

    OBJECT_CLASS_PROPERTY_ADD_STR(oc, MachineState, kernel_filename,
                                  "kernel", prop_allow_set_always);

?

Paolo
