jackqdyulei c76bb78758 Make BatteryDatabaseManager singleton ...

In BatteryTipLoader, two threads may access BatteryDatabaseManager
simultaneously. In this case thread A may close the database thread B
holds, then settings will crash.

In this cl, we make the BatteryDatabaseManager as singleton and
synchronize all the database related method. Then it shouldn't have
the crash anymore.
