Trust the beta innovations more compated to the TAS innovations.
That should help with detecting real airspeed failures even with
a dynamic wind estimate (as long as vehicle doesn't fly straight)

Increasing the wind process noise results in a more dynamic
wind estimation, which is capable of catching fast-varying
winds. As wind is used in the lateral guidance it's important
that we don't filter it too much.
Furher the gate of the airspeed fusion is increased, to
reduce the likelihood of airspeed fusion stopping due to
dynamic wind conditions. The airspeed is validated in
the airspeed validator (EKF consumes the validated one).

Reduces flash usage by ~16KB.
- compress formats at build-time into a single string with all formats
- then at runtime iteratively decompress using
https://github.com/atomicobject/heatshrink
- if not in air the accel noise is doubled
- if landed don't init unless GPS velocity is non-negligible
- when inactive continue seeding with EKF gyro bias
- reset yaw estimator if GPS fusion is stopped
Has options *None where the check is disabled, and *Warning, where only a warning is
published (which replaces the high wind warning from the COM_WIND_WARN limit).

There is no reason to keep an uncertainty on the origin as it is then
already contained in the local position estimate when GNSS data is fused
in the filter.
The command is sent by a dedicated mavlink command and forwarded to the fixed wing position controller.
The pattern is defined by the radius of the major axis, the radius of the minor axis and the orientation. The pattern is then defined by:
The upper part of the pattern consist of a clockwise circle with radius defined by the minor axis. The center of the circle is defined by the major axis minus the minor axis away from the pattern center.
The lower part of the pattern consist of a counter-clockwise circle with the same definitions as above.
In between, the circles are connected with straight lines in a cross configuration. The lines are always tangetial to the circles.
The orientation rotates the major axis around the NED down axis.
The loitering logic is defined inside its own class used by the fixed wing position control module. It defines which segment (one of the circles or lines) is active and uses the path controller (npfg or l1-control) to determine the desired roll angle.
A feedback mavlink message is send with the executed pattern parameters.
This switches from the horribly intertwined ringbuffer implementation to
the new VariableLengthRingbuffer implementation.
By ditching the previous implementation, we fix MAVLink message
forwarding, which didn't work reliably. The reason it didn't work is
that multiple mavlink messages could be added but only one of them was
sent out because the buffer didn't keep track of the messages properly
and only read the first one.

* mission_base: reset inactivation index when user set a new mission index, or mission is reset.
* mission_base: check Climb required always on current mission item
This prevents the mavlink transmit loop from waiting on the module mutex
thus not stopping transmissions when the mutex is already taken.
This can happen when calling `mavlink status` from the mavlink shell,
where `Mavlink::get_status_all_instances()` takes the mutex and then
prints the status via pipes to the mavlink transmit buffer.
If that pipe cannot be emptied a deadlock happens.
Since the MavlinkReceiver thread also waits on the module mutex, both
reception and transmission of Mavlink packets are then prevented thus
disabling communications entirely.
