* EKF: Replace in-lined Tait-Bryan 312 conversions with function call
Also remove unnecessary operations
* EKF: Remove unnecessary update of external vision rotation matrix
* EKF: Use const
* EKF: use const
* EKF: don't use class variable as a temporary variable
* EKF: update comments
* EKF: Improve efficiency of yaw reset
Use conversion from rotation matrix to Euler angles instead of quaternion to euler angles.
* EKF: use const
* EKF: remove un-used struct element
* EKF: more descriptive function name
* EKF: use existing matrix row operator
* EKF: remove unnecessary rotation matrix update
* EKF: Use square matrix type
* EKF: Improve protection for bad innovation covariance
* EKF: Use matrix library operations
* EKF: Replace memcpy with better alternative
memcpy bypasses compiler sanity checks and is unnecessary in this instance.
* EKF: Split EKF-GSF yaw reset function
Adds a common function to support yaw reset that can be used elsewhere.
* EKF: Use common function for quaternion state and covariance yaw reset
* EKF: Replace inlined matrix operation
* EKF: Use const
* EKF: Change accessor function name
* EKF: Use const
* EKF: Don't create unnecessary duplicate variable locations
* EKF: Remove duplicate covariance innovation inverse
* EKF: Don't create unnecessary duplicate variable locations
* EKF: Rely on geo library to provide gravity
* EKF: Improve protection from bad updates
* EKF: Reduce effect of vibration on yaw estimator AHRS
* EKF: Improve yaw estimator AHRS accuracy during manoeuvre transients
* EKF: do not fuse multiple times the same height
The _fuse_height flag was never set to zero, hence the fusion was called
at each iteration, even if no new data is available.
The effects were: high CPU usage and virtually less measurement noise
due to multiple fusion of the same sample
Also remve unused variables
The implementation before this change had two timeouts, a hard-coded
timeout of 0.5 seconds as well as a by param configurable timeout with
certain failsafe actions set.
This change aims to fix two problems:
1. The hard-coded offboard timeout can be triggered easily with sped up
lockstep simulation. Since i t is hard-coded it can't be adapted to
the speed factor.
2. The offboard signal can time out but no action will be taken just
yet. This means we end up in an in-between stage where no warning or
failsafe action has happened yet, even though certain flags are set
to a timeout state.
This patch aims to fix this by unifying the two timeouts to the existing
configurable param. The convoluted double timeout logic is replaced by a
simple hysteresis.
For anyone that has previously not changed the default timeout param (0),
the param will now be changed to 0.5 seconds which reflects the
previously hardcoded time. For anyone with a specific timeout
configured, the behaviour should remain the same.
Also, going forward, timeouts lower than 0.5 seconds should be possible.

When lockstep is enabled and LPE is not running, the
attitude_estimator_q needs to publish ekf2_timestamps in order to signal
to the simulator module that it has fully run.
This essentially fixes flying in lockstep when SYS_MC_EST_GROUP is 3.
