- sending protocol
- uorb event message & template methods for argument packing
- libevents submodule to send common events and handle json files
- cmake maintains a list of all (PX4) source files for the current build
(PX4 modules + libs), which is used to extract event metadata and
generate a json file
- change default FFT length (1024 -> 512)
- this doubles the update rate because half the number of samples are required for each
- decrease number of peaks (4 -> 3)
- so far 3 seems to be sufficient on most vehicles
- increase median filter window (3 -> 5)
- decrease SNR requirement (likely needs to be configurable)
- IMU integrator set max dt based on final return size (uint16)
- improve integration consuming gyro as needed then integrate all available accel until caught up
- increase required number of samples for sensor rate measurement (online Welford mean)
Because based on the numerous complaints it was disabled by default
(only velocities above 10m/s were limited)
and since then no one intentionally used it anymore. But
there were some minor investigations of drones not reaching
their maximum speed which always showed 10m/s.
The same way like in loiter. This should be further unified in the code
but at least we can increase safety in the case the takeoff altitude is
very high and the vehicle never reaches it but looses links.
The condition to get valid requires a low variance and test ratio. but
to stay valid, only the variance is required.

- IMU init requires valid published data (device ids, etc)
- orb_group_count will include advertised instances before data is published, so this can't be used to throttle IMU init attempts
* commander: send parachute command on termination
This sends the DO_PARACHUTE command to parachute component.
* commander: fix lying comments and printf
* commander: use one flag for termination triggered
This merges the duplicate flags _flight_termination_triggered and
_flight_flight_termination_printed.
* commander: correct variable name
* commander: always send tune with parachute
* commander: fix target_component for parachute cmd
The previous changes were wrong in that all commands were now sent to
the parachute component which doesn't make any sense. Of course only the
parachute command should be sent there.
