Unfortunately the constraints cannot be implemented using the
_constraints because the controller uses that directly. This
causes discontinuities in the velocity and/or accel at various
points of the flight. In particular this was used in Takeoff.
Instead this was done by changing target accel/velocity in the
jerk-optimal velocity planner for Z.
The modified statements are intended to
1. Set a new Z position setpoint that is equivalent to the current distance
to ground setpoint,
and
2. Set a new distance to ground setpoint that is equivalent to the current Z
position setpoint.
They are only called in terrain hold mode, when activating/deactivating the
holding (typically when coming to a stop and when starting to move again).
The setpoints take the current control error into account, but because the
control error is added, not subtracted, the result is that the new setpoint
is 2 times the control error off from the old setpoint, instead of being
at the same spot as the old setpoint.
Extend the get_freefall_state() from MC land detector to have a VTOL-specific
one that just enables free fall detection if in rotary wing or transition mode.
This is done to prevent wrong free-fall detected warnings while doing low-G maneuvers
(parabolic flights). Land detection is anyway disabled in FW flight for VTOL so
no logic change.

The problem with printing the exception was that starting with
Python 3.6 the ImportError is yet another (sub) exception called
ModuleNotFoundError which can't be printed as a string and then triggers
another exception:
```
Traceback (most recent call last):
File "/home/julianoes/src/Firmware/Tools/serial/generate_config.py", line 11, in <module>
import jinja2
ModuleNotFoundError: No module named 'jinja2'
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "/home/julianoes/src/Firmware/Tools/serial/generate_config.py", line 13, in <module>
print("Failed to import jinja2: " + e)
TypeError: must be str, not ModuleNotFoundError
```
As per @bkueng's suggestion the easiest is to cast the exception to str
and that way prevent the second exception.
Channels belonging to a certain timer were not all grouped together.
This is required by the .first_channel_index and .last_channel_index data
members.
We introduce a new mixer geometry to solve the problem.
Use yawrate setpoint from weather vane only if velocity setpoint is small
(smaller than half the cruise velocity)

- remove gloabl variable and instead give back forward_thrust from function
- give back increased vertical thrust from fct thrust_compensation_for_tilt()

-move pusher assist functionality into vtol_type class and adapt it to also
work for tiltrotor VTOLs (pitch rotors down to accelerate forward)
-for tiltrotor: compensate for lost lift due to tilt by increasing the throttle
-enable pusher / tiltassist also in altitude mode

This is done to test the recovery function of the estimator in case
of divergence or sudden extreme hover thrust change.
Also specify seed of random generator
with measurement noise auto-tuning
The purpose of this estimator is to improve land detection and vertical
velocity feedforward
Recovery strategy:
This is required when the setpoint suddenly changes in air or that the
EKF is diverging. A lowpassed test ratio is used as a trigger for the recovery logic
Also, a lowpassed residual is used to estimate the steady-state value
and remove it when estimating the accel noise to avoid increasing the
accel noise when the redisual is caused by an offset.
- it does nothing useful

* add support for unmanned underwater vehicles:
* airframe uuv_generic + uuv_hippocammpus including mav_type = 12 for submarines
* mixer for UUVs with X-shaped thruster setup similar to quadcopter
* add module uuv_att_control for underwater robot attitude control
* add rc.uuv_defaults/apps for autostarting e.g. ekf2 and uuv_att_control app
* Add param for software flow ctl on 3DR radios
* Dont reset telemetry type on radio timeout
* Treat 3DR radio as generic link type
* Rename 3DR to SiK radio
new versions of logger does not allow to log multiple instances of a topic when using 'logger_topics.txt'
This commit restores the default behavior (log all instances of a topic) and ad the option to specify an instance to log
