aaaae9a222 AP_AHRS: added get_fly_forward() method
will be used to detect a copter

9a5ecc9541 AP_AHRS: use primary accel for accel_ef
Logs from Randy show that the copter INav code can't handle the
accelerometer sensor changing.

b53496d470 AP_AHRS: choose the best accelerometer at each drift correction step
this greatly reduces the impact of aliasing on accelerometers by
choosing the accelerometer that produces the smallest error term in
DCM. The difference can be quite dramatic on the Pixhawk.

0b45d2bc06 AP_AHRS: removed the AHRS_GPS_DELAY parameter
the best value has turned out to be 1, and tweaking it has not turned
out to be useful, so this simplifies the code in preparation for
adding the anti-aliasing handling with multiple accelerometers

f321a5f241 AP_AHRS: Change airspeed_estimate to const in children of AP_AHRS
Allows roll/pitch controllers to use DCM's airspeed estimate. Thanks to Kevin Hester for assistance in finding this.
