Andrew Tridgell a427abab0d AP_AHRS: allow for fallback to DCM in quadplanes
this adds the necessary functions to allow for flying a quadplane on
DCM as an emergency fallback. It sets the NavGainScalar to 0.5 to
reduce the VTOL controller gains to allow planes to cope with the
higher lag of DCM

Harshit Kumar Sankhla b5b3298f0a AP_AHRS: get airspeed estimate from non-primary instances too
with multiple airspeed sensors and airspeed affinity in EKF3,
it is possible to have switched over to a lane not using the
primary airspeed sensor, so AHRS should know which airspeed
sensor to use, i.e, the one being used by the primary lane.

Andrew Tridgell 0ccaa5bcba AP_AHRS: removed create() method for objects
See discussion here:

  https://github.com/ArduPilot/ardupilot/issues/7331

we were getting some uninitialised variables. While it only showed up in
AP_SbusOut, it means we can't be sure it won't happen on other objects,
so safest to remove the approach

Thanks to assistance from Lucas, Peter and Francisco

position)

Mathieu OTHACEHE 152edf7189 Global: remove mode line from headers

estimate. Based on discussions with Jon Challinger

Andrew Tridgell 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.

Andrew Tridgell 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
