Implement new functions qemu_register_resettable() and qemu_unregister_resettable(). These are intended to be three-phase-reset aware equivalents of the old qemu_register_reset() and qemu_unregister_reset(). Instead of passing in a function pointer and opaque, you register any QOM object that implements the Resettable interface. The implementation is simple: we have a single global instance of a ResettableContainer, which we reset in qemu_devices_reset(), and the Resettable objects passed to qemu_register_resettable() are added to it.
