- added support for BQ40Z80 based battery
- added performance counter for interface errors
- added SMART_BATTERY_INFO mavlink message
- general code cleanups and optimization
- fixed: void flooding the log in case of interface error
- fixed: using _batt_startup_capacity instead of _batt_capacity for discharged_mah
- update: read manufacture_date
- update: get _cell_count from parameter and not const 4
- update: avoid re-reading data that has already been read and stored on class already
- currently the battery type defined by BAT_SMBUS_MODEL parameter and not by auto detection
This moves the handling of the BAT%d_SOURCE param inside of the battery
library. Users of the library now pass the source instead of the flag
whether to publish. The battery library then checks if the source is
selected using the param and publishes accordingly.
Since we removed the strange system_source flag, we now need to look at
all batteries in commander.
For current estimation - I think - it makes sense to sum them up.
* Enhancement: State of health, and max_error value is added. Both shows battery health of SMBUS smart battery.
* Enhancement: BAT_C_MULT parameter is introduced. This is for high-current capable SMBUS-based battery.
As SMBUS only provides 16-bit for current, it could only be +-32768mA which is about +-32A.
But with proper treatment, it could be extended with little accuracy loss.
This factor can be set for individual battery system with available information.
* Relative SOC introduced. Proper SMBUS battery should provide percentage of remaining battery
directly. Therefore it does not have to be computed like before.
* State of Health introduced. Proper SMBUS battery should provide SOH value.
* Max error: this shows estimation error of BMS.
* Enhancement: With smart battery, precise estimation of time remaining is provided
with impedance track. It is unit of minute, so 60 seconds multiplied.
Update rate of this is not fast, but very useful.

* Updated and expanded batt_smbus to work with bq40z50-R2. Expanded battery_status.msg. Fixed mavlink_messages.cpp temperature, added commented out expanded battery_status.msg parameters for future mavlink expansion.
* Changed errx to PX4_ERR
* Added PX4_ERR returns
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.
