Some batteries can signal when an internal fuse was blown. In such a case POWER_SUPPLY_HEALTH_DEAD is too vague for userspace applications to perform meaningful diagnostics. Additionally some batteries can also signal when some of their internal cells are imbalanced. In such a case returning POWER_SUPPLY_HEALTH_UNSPEC_FAILURE is again too vague for userspace applications to perform meaningful diagnostics. Add new health status values for both cases.
