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.

AP_AHRS: standardize inclusion of libaries headers
...
This commit changes the way libraries headers are included in source files:
- If the header is in the same directory the source belongs to, so the
notation '#include ""' is used with the path relative to the directory
containing the source.
- If the header is outside the directory containing the source, then we use
the notation '#include <>' with the path relative to libraries folder.
Some of the advantages of such approach:
- Only one search path for libraries headers.
- OSs like Windows may have a better lookup time.

AP_AHRS: fixed calls to DCM in parent class
...
use_compass() and reset() are common to AP_AHRS_DCM and
AP_AHRS_NavEKF. As AP_AHRS_NavEKF is a child of AP_AHRS_DCM, when we
call use_compass() from within AP_AHRS_DCM we actually end up calling
AP_AHRS_NavEKF::use_compass().
This has the effect of disabling the compass in DCM when EKF is active
and EKF has decided not to use the compass. That means that the DCM
yaw (and in fact the whole attitude) can get badly off while EKF is
enabled, making DCM an ineffective fallback if EKF fails.
The fix is to call the specific class versions of use_compass() and
reset()
