system_source - This battery status is for the brick that is
supplying VDD_5V_IN
priority - Zero based, This battery status is for the brick
that is connected to the Power controller's
N-1 priority input. V1..VN. 0 would normally be
Brick1, 1 for Brick2 etc
Battery now assigns connected from the api in the
updateBatteryStatus, as well as system_source and priority
The commander used to consume the battery_status topic and write the
contents after some calculations into the system state. Instead, the
calculations now happen in library calls in systemlib/battery.
This moves the battery fields out of the vehicle_status message into the
battery_status topic.
This brought quite some changes in all modules that need battery
information. The current state is compiling but untested.
