AR_AttitudeControl: add speed-control-active method
...
allows caller check if speed controller if active
also consolidated other methods to use this check to reduce a little bit of duplicate code

AR_AttitudeControl: caller provides dt instead of calculated internally
...
This allows the vehicle's main loop rate to be used instead of an internally calculated dt which suffers from jitter

AR_AttitudeControl: separate speed limiting to new method
...
This allows the desired speed limiting (by acceleration) to be done before the speed-to-throttle PID controller is run.
This is required so the avoidance calls (which work on the desired speed) can be run after limiting but before the PID controllers

AR_AttitudeControl: add angular accel and rate limits
...
This limits the change in desired turn rate to reduce impossible requests which should help avoid overshoot
Also add rotation rate limit to turn-rate controller

AR_AttitudeControl: throttle and steering control library
...
Throttle controller has these advantages over existing controller:
based on velocity in vehicle's forward-back axis rather than ground-speed
straight-forward PID controller using speed error as input
speed control acceleration limts
stop control slows vehicle smoothly
configurable filtering
Steer controller has these advantages over existing controller:
output scaled properly for skid-steering vehicles
layered P and PID controller for angular error and rate control
configurable filtering
