Reimplement qemu_register_reset() via qemu_register_resettable(). We define a new LegacyReset object which implements Resettable and defines its reset hold phase method to call a QEMUResetHandler function. When qemu_register_reset() is called, we create a new LegacyReset object and add it to the simulation_reset ResettableContainer. When qemu_unregister_reset() is called, we find the LegacyReset object in the container and remove it. This implementation of qemu_unregister_reset() means we'll end up scanning the ResetContainer's list of child objects twice, once to find the LegacyReset object, and once in g_ptr_array_remove(). In theory we could avoid this by having the ResettableContainer interface include a resettable_container_remove_with_equal_func() that took a callback method so that we could use g_ptr_array_find_with_equal_func() and g_ptr_array_remove_index(). But we don't expect qemu_unregister_reset() to be called frequently or in hot paths, and we expect the simulation_reset container to usually not have many children.
