Log Message:
- Rename ENVSYS_BATTERY_STATE units to ENVSYS_BATTERY_CAPACITY and
  introduce ENVSYS_BATTERY_CHARGE, which is the same than an Indicator and
  it's used to know if the battery is currently charging or discharging.

- Require two sensors at least for SME_CLASS_BATTERY to make the low-power
  condition work: a ENVSYS_BATTERY_CAPACITY plus ENVSYS_BATTERY_CHARGE.

- Simplify sme_event_check_lowpower() and make it check the required
  sensors in the SME_CLASS_ACADAPTER and SME_CLASS_BATTERY classes.
  If the acadapter is not ready, trust the state returned by the battery
  device.

Based on suggestion from joerg@.
