* a request for setting the '_HASH_CHECK' parameter is handled differently
than the same request for a standard parameter. Make sure we don't actually
try to set the parameter.

The threads running commands for clients through the Posix daemon used
to write to a char buffer through snprintf (etc.) which was then written
directly to the file descriptor, whereas in the other case printf
(etc.) was used to write to stdout (FILE*). Both versions used some
macro's and repeated code to have the same output.
This change unifies these two cases by using a FILE* in both cases. The
(line) buffering is done by the standard C library's implementation
(just like with stdout), and px4_log.c now uses the same code in all
cases (using fprintf, etc.) for printing (colored) output.
* attitude and rate setpoint message: use 3D array for thrust demand
* FixedWingAttitudeControl: rework airspeed scaling
* move airspeed and scaling calculation into separate method
* if vtol in hover and airspeed disabled use minimum airspeed instead of trim airspeed
When switching back from rate to attitude control, the code depended on a
vehicle_control_mode topics update, but the publication frequency of that
is low. So the switch was noticeably delayed.
- better in terms of dependencies:
- the position controller code depended on position topics for yaw
- mc_pos_control does not have to be run for Stabilized mode
- the code path is much simpler, and thus less error prone. This is
especially important since Stabilized is often used as a fail-safe flight
mode.
Previously when switching e.g. from stabilized from acro, the stabilized
flight task kept running and publishing setpoints.
Luckily it caused no problems, but the log showed arbitrary attitude
setpoints.
As there is only one bit used in 'flags', and it is only used in case
update_interval is not null, we can move the bit to UpdateIntervalData.
The size of UpdateIntervalData does not increase (on 32 bit).
Reduces RAM usage by 3.6KB (tested on a Pixracer).
- move the update after the integration: a new computed jerk has an impact at the next epoch only
- add jerk reduction in case of too large integration time: when a jerk of "min_jerk" during dt is too much
- add jerk reduction if the integration time is larger than the predicted one and that integrating that jerk would lead to an acceleration overshoot
- rename some variables
