DataFlash: rename Log_Write_SERVO to Log_Write_RCOU
Plane: rename Log_Write_SERVO to Log_Write_RCOU
Copter: replace Log_Write_Motors with Log_Write_RCOU
Copter: more complete RC output reporting to GCS

Radio outputs are pulled from hal.rcout instead of from motors library
which provides more complete reporting because it includes output from
sources like the camera and mount libraries.
Copter: make motor_out array private

With new method of logging rc outputs access to the motor_out array is
not longer required
Tri: call output_min at end of motors test

Minor change to comments
SingleCopter: motor test flaps servos in order
Copter: motor matrix comment change
TradHeli: remove use of motor_out array

No longer required for logging purposes as we have RCOU
Copter: rename nav_yaw to control_yaw
Copter: firmware to ArduCopter V3.2-dev
Copter: remove yaw_in from ATT dataflash msg
Copter: combine nav_roll and control_roll

Control_roll, control_pitch now always hold the desired lean angle
whether it be from the pilot or autopilot.
AP_Motors: fix example sketch
PX4: added support for the MPU6000 on the v2.4 Pixhawk
SITL: Add barometer drift parameter to the SITL library
SITL: Wire in random noise and fixed drift for the SITL barometer
SITL: Wire in basic support for SITL downward-looking sonar sensors
SITL: Add noise and glitching behaviour for the sonar sensor
SITL: moved airspeed pin to pin 1

keep it separate from the sonar, allowing both to be used at the same time
