This adds two battery parameters that need to be monitored constantly:
remaining_capacity and full_capacity (that one only changes occasionally,
but we have to notify the AP when it does).
It also adds the is_present field to indicate whether the battery is
physically present or not (when we can tell), so we know whether to try to
wake up a deep-discharged battery.
Along with that, we clean up the error flags to provide indication of which
fields were unable to be read, and replace the manual logical-or of all
errors as they were set with a bitmask (BATT_FLAG_BAD_ANY).
No functionality is changed, only new & better information is provided for
