It's possible to apply impl_vmstate_transparent for cell::Opaque and then impl_vmstate_forward for timer::Timer. But binding::QEMUTimer shouldn't be used directly, so that vmstate for such raw timer type is useless. Thus, apply impl_vmstate_scalar for timer::Timer. And since Opaque<> is useful, apply impl_vmstate_transparent for cell::Opaque as well.
