Rover: use base-class auxsw handling
Rover: factor out do_aux_function_change_mode
Rover: move mode number enumeration to be in Mode:: namespace
Rover: move mode switch handling to RC_Channel
Rover: rename control_modes.cpp to RC_Channel.cpp
Rover: move motor_active() to be a method on the motors class
This separates the default/maximum speed used in Auto, Guided, RTL and SmartRTL from the CRUISE_SPEED which is used as the base for the speed-to-throttle controller (along with CRUISE_THROTTLE)
new mode class member _desired_speed_final holds target speed at destination
main vehicle code passes heading to next waypoint into auto mode.
we do not provide heading when delaying at waypoint which signals we wish
auto-mode calculates final speed at destination which allows vehicle to
make turn within value of WP_OVERSHOOT parameter assuming vehicle turns at
maximum lateral acceleration.
also direct throttle nudge replaced with speed nudge
calc_speed_max estimates vehicle's top speed based on cruise-speed and
cruise-throttle
steering mode now provides total target speed instead of using speed plug
throttle nudge
motor limits provided to attitude control to stop i-term buildup
uses negative desired speed instead of reversed flag
reporting to GCS uses new throttle controller
braking is simply enabled and allows a reverse motor output regardless of vehicle
speed
move throttle_slew_limit and THR_SLEWRATE parameter
move have_skid_steering to library
move mix_skid_steering to library's output_skid_steering method
move radio.cpp's output channel initialisation to motor's init method
use motors.get_throttle and get_steering instead of getting from Servo objects
use motors.set_throttle and set_steering instead of setting to Servo object
AP_Arming::arming_required is replaced with SAFE_DISARM parameter
