Fix concurrency issue with BatteryUsageStats
BatteryUsageStats is created under a BatteryStatsImpl lock. One of
the elements of BatteryUsageStats is the battery history buffer Parcel.
Once the BatteryUsageStats object is created, the BatteryStatsImpl lock
is released and the history buffer parcel continues to be appended
by BatteryStatsImpl. The Parcel may even be reset altogether if the
battery stats session is reset. The BatteryUsageStats object is parceled
during the getBatteryUsageStats binder call. Any modification of the
history buffer concurrent with parceling causes a crash.
