EKF: Improve handling of non position mode large position innovations
...
These changes fix a bug that allowed IMU gyro errors that cause large tilt errors prior to start of aiding not resulting in large innovation test ratios.

rng height: reset to baro using common logic
...
The failsafe from rng height to baro height should occur after a reset
to baro triggered by the controlHeightSensorTimeouts function and not in
the fusion selector.
Until now, the EKF was fusing baro measurements between rng updates if
the range finder ODR was slower than the EKF update rate. This is not
the case anymore as the height reset occurs after 5 seconds.
The unit test has been extended to show this behavior.

gps_alt: do not scale up reported gps vertical accuracy
...
The comment said that the horizontal accuracy needs to be scaled up
using the typical epv/eph ratio but the epv (vacc) is already available,
so no scaling is required.

flow: restructure optical flow control logic ( #928 )
...
- extract motion checks performed on ground
- move all non-timing check to controlOpticalFlowFusion. This simplifies and standardirzes the setOpticalFlowData function. Furthermore, in some cases (SITL, PX4Flow), the dt is forced to 0 when the quality is 0 (which is usual on ground) so the ekf needs to ignore those values on ground to initialize properly the flow fusion.
- add filter convergence test
- move check for dt time max in setOpticalFlowData
- in the simulator, do not update dt as this is the sensor integration
period.
