AP_AHRS: don't reject airspeed using EKF if dead-reckoning
...
when dead-reckoning the EKF wind estimate can diverge from reality,
leading to us rejecting a valid airspeed sensor. We are best off
trusting airspeed if we are dead-reckoning

AP_AHRS: if DCM has no yaw source then don't fallback when hovering
...
this copes with quadplanes with no compass. With a compass we are
better off using EKF when not in fly-forward as it will give better
height control.
This makes QHOVER for takeoff in quadplanes with no compass a lot more
flyable

AP_AHRS: auto-enable EKF3 for misconfiguration
...
this fixes a "climb away" in quadplanes when AHRS_EKF_TYPE=2 and
EK2_ENABLE=0. The user has ARMING_CHECK=5390 to disable key arming
checks, and the plane flew on DCM as the configured EKF wasn't
enabled.
This resulted in AHRS::get_origin() returning false as it couldn't ask
EKF2 for the origin (as EKF2 was not enabled or instantiated)
The result was an incorrect calculation for target height during the
descent stage of QRTL, resulting in a climb away until the user took
over

AP_AHRS: fixed use of filtered gyro with DCM active
...
we need to overwrite _omega with the filtered gyro value, so we get
both the low pass filter and the notch filters. Otherwise we will fly
with very high noise gyro data
this also fixes the accel_ef_blended to use the filtered accel. It is
not blended, and removing "_blended" from the API will be worthwhile
as a followup
