AntennaTracker: fixed autodoc format errors
autotest: add AntennaTracker autodoc to autotest.diydrones.com/Parameters
Frame Parameters: 3DR AERO RTF

Updated 3DR AERO RTF parameters
AP_RangeFinder: make values clearer for APM2
* Frame Parameters: 3DR AERO RTF

Updated RLL2SRV_P parameter
Notify: remove ToshibaLED support from APM

This saves about 1k of precious flash
Copter: remove compass learn of offsets

This saves 1k of flash and the interference on most copters makes this
option unusable anyway.
Copter: range check ACRO_EXPO to be no more than 1
Copter : Distinguish between EKF and INAV errors
Copter: Added support for V-Shaped and A-Shaped VTail Quadcopter frames

Signed-off-by: NullVoxPopuli <LPSego3+dev@gmail.com>
Copter: add A-Tail to FRAME parameter description
DataFlash: moved UBX logging headers to DataFlash
AP_GPS: moved UBX log headers to DataFlash

headers were not always being written
Copter: set GPS non-blocking

the new GPS driver only ever needs a non-blocking port
HAL_PX4: prevent read past end of buffer
HAL_VRBrain: prevent read past end of buffer
Copter: add ACRO_EXPO param values
Copter: remove inav check

the EKF check works reliably but attempts to check the inertial nav for
errors has not been successful.  I could not find a way to reliably
catch flyaways without also introducing false positives (and thus
unwanted LANDings)
AC_AttitudeControl_Heli: Create Flybar Passthrough flag which will be used for control pass-through.
TradHeli: Add pointer for pilot roll/pitch inputs to attitude_control constructor. To be used for flybar passthrough.
