[Position|AutoLine]SmoothVel - Update position and velocity states of the trajectories in case of EKF reset. Until now, only the position reset on XY axis was properly handled. Now, xy, vxy, z and vz are handled

   This also fixes a typo in the GPIO defines

ManualPositionSmoothVel - Force velocity and acceleration setpoints to zero if the velocity setpoint is smaller than 1mm/s and that the acceleration setpoint is null

ManualSmoothVel - Set jerk to 1.0 during position hold to help the optimizer to converge towards 0 vel and acc

mc_att_control: replace math::min() and additional limit logic with math::constrain() calls (#11658)

- fixes #11666

It turns out that we can fix the unit tests of the lockstep_scheduler
just by checking if `passed_lock` is not `nullptr`.

Without this check, the unit tests segfaulted.

This fixed running `make tests` on Arch Linux where Python 3 is the
default.

VTOL: unset v1.9 roll direction safety check param for builtin airframes

This inversion matches the fixed sign in the commands generated
by the VTOL attitude controller.
This commit, combined with the previous commit, should have no effect.
For safety, it is recommended to check the direction of roll control
surfaces before flight.

* FlightTaskAuto - Explicitly check is _triplet_target is finite to decide if the target has to be updated or not. If the _target is NAN, always try to update it to get a valid setpoint.

Bug Fixes:

https://github.com/PX4/ecl/pull/586 - EKF: fix covariance and output filter buffer initialization
https://github.com/PX4/ecl/pull/590 - EKF: Fix innovation in fuseDeclination()

Enhancements:

https://github.com/PX4/ecl/pull/543 - ekf_helper: add more useful methods to interface with the covariances
https://github.com/PX4/ecl/pull/588 - Add unit tests for DataValidator

Note:

https://github.com/PX4/ecl/pull/543  has required a change to how the state variances are accessed .
