Twizy V2.6.4:
- RT-GPS-Log extended by power data
- Fixed a bug with distance measurement (wrong power efficiency)
- Power statistics just show power sums if not driven
- Rounding of car_speed
12V measuring; net msg queue; watchdog timer

- Changed 12V A/D auto acquisition time to 8 TAD = 12.8 us
  (should fix 12V misreadings)

- Reworked check for pending msg sends in net_state_ticker1()
  to avoid send conflicts with vehicle_idlepoll()

- Raised watchdog timeout to 16 seconds; with multiple sends
  8 seconds can be reached under normal conditions
