Battery stats more wake history, power save mode. 

Add new option for battery stats to record the full wake
lock history, and recording the current power save mode.

Also add in some additional error constants when generating
Binder error exceptions.

And fix issue #14974572: Avoid repeating wakeup_reason at
the beginning of history
