01fb16b3b0 AP_AHRS: relax arming checks for inactive AHRS types 
When using an EKF as ride-along we should not fail arming if it has
inconsistent yaw between its lanes. This is especially important when
using external yaw or GPS yaw with EKF3, where yaw is expected to be
bad with EKF2.

The check on DCM is based on the existance of an AHRS view. This is so
that tailsitters do not get arming failures due to the inability of
DCM to cope with being nose up

43e83f18be AP_AHRS: do not send EKF_STATUS_REPORT from DCM 
This means that even if you configure DCM as your primary you won't get
its status.

Given the status was currently garbage, this isn't necessarily a bad
thing at the moment.

9dbd9d1e06 AP_AHRS: call INS update in AP_AHRS::update w/o holding data sem 
We shouldn't be holding the data semaphore while waiting for the samples
- lots of things might be unnecessarily blocked

DCM's update function doesn't need to take the semaphore as it is
already taken by AP_AHRS

53e7436525 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

73bad9fd2d AP_AHRS: move fly_forward flag to front end 
This same flag is requested by the DAL so AN_NavEKF2 and AP_NavEKF3 can
use it in their estimates - so AP_AHRS_DCM accessing it via the same
mechanism is not out-of-shape

f557d41145 AP_AHRS: rotate quaternions into vehicle body frame 
DCM was having it both ways depending on whether it was

These are mostly uses for reporting, in which case you would expect the
quaternion to match the eulers.
