Andrew Tridgell 724301ea53 APM_Control: make 2nd reduction of P smaller
this prevents severe P reductions when we get a small oscillation
glitch after we've already got the primary P gain

Randy Mackay e85a95f21c AR_AttitudeControl: reduce some param defaults
These reductions are based on experirence helping users setup new vehicle.  In the vast majority of cases the existing values are too high

STEER_ANG_P is the default for the angle-to-rate controller and is used during pivot turns.  This value may still be slightly too high.
STEER_RATE_MAX is the maximum turn rate so the new value allows a 360 turn in 3 seconds
STEER_ACCEL_MAX is the acceleration for the turn rate meaning a vehicle can get to 120 deg/sec in 1 sec
THR_ACCEL_MAX is the maximum acceleration.  This new value means a vehicle can accelerate to 1m/s in 1 second.

process

Ben Wolsieffer 68ee2c21dd AP_Control: apply pitch rate limit to turn coordination
At high bank angles, for example when rolling to/from inverted, a large turn
coordination pitch rate offset is requested. Before this patch, this offset was
not subject to the configured pitch rate limit, which could result in pitch
controller integrator windup.
