Silvan Fuhrer 49c363674a FW Position Control: only prevent automatic aborts if already flaring, but allow manual aborts

Silvan Fuhrer 94d44c40a7 FW Position control: remove param FW_CLMBOUT_DIFF and instead use hardcoded 10m for clearing aborted flag
Use kClearanceAltitudeBuffer for it, which is also used to ensure that during takeoff an
altitude setpoint above the clearance altitdue is set.

Thomas Stastny f23328d14f fixed-wing landing: ramp in flaring throttle setpoints from last throttle state to keep control continuity
- also put flaring internal states into a struct to organize a bit
- one concern with blending the throttle setpoint like this with the flare time param is that folding prop belly landing airframes may want to have a separate param for shorter throttle kill and still use the flare time ramps for everything else

Thomas Stastny 928be2958d fixed-wing landing: continue to follow path throughout flare
abruptly changing to a heading setpoint on flare can cause the aircraft to roll and deviate from the runway, this commit
- maintains path following control during the flare not to disrupt the tracking just before touchdown
- (unfortunately for crosswind landing) removes the body axis alignment for runway bearing - this is a compromise

to achieve both runway bearing body axis alignment AND a specific touchdown point, either
1. the wind would need to be considered, and an appropriate diagonal approach (obstructions allowing)  defined to the runway
2. slip control added, keeping path following outputs only commanding roll (controlling airspeed vector) and using yaw-rate command (only actuated by e.g. rudder) to align body axis with the runway

- input correct units to rwto pitch constraint getters

Thomas Stastny a4349193b5 fixed-wing runway takeoff: climbout at specified takeoff airspeed and max climb rate
TECS climbout mode was used for takeoff climbout, which puts throttle to full and does not regulate a specific airspeed.
This commit sets the desired takeoff airspeed explicitly and allows max climb rate to track the ascent.

Thomas Stastny 47963b5b67 fixed-wing runway takeoff: define explicit takeoff speeds
previously a scale factor param on min airspeed was used to define the climbout airspeed for runway takeoff
additionally, the rotation speed was defined by another hardcoded scale on top of the previously scaled min airspeed
this commit explicitly defines a takeoff speed and rotation speed for runway takeoff in params, with option to disable

Silvan Fuhrer c4c94febfa FW Pos C: clearly define FW_AIRSPD_MIN as stall+margin, and automatically increase f(load_factor)
Previously the minimum airspeed setpoint was adjusted to the load_factor compensated
stall speed, which, when the stall speed was set without margin, gave the controller
no room for error (the vehicle would stall if the controller has even a small airspeed
error).

if armed (as they are pure failsafe modes). Also allow though to enter them even if
the position setpoint(s) are invalid, as they are not needed.

Silvan Fuhrer 67b2c835e0 FW Positon control: do not use position_setpoint.valid to validate current position_setpoint
Instead of checking the .valid flag of position_setpoint, check for ISFINITE() of lat, lon, alt
    when pulling the position_setpoint triplet. This fixes problems where the .valid flag didn't
    reflect the proper state of the setpoint (e.g. .valid was true, .lat though NAN)

Silvan Fuhrer f9b6edab07 Navigator/FW Position Control: VTOL front towards specified transition heading if available
If the current yaw setpoint is valid we should use it to make the transition in this direction.
For a VTOL_TAKEOFF the yaw_setpoint is used to specify the transition direction (the
vehicle is aligned towards it and then transition is started). The current yaw can be
a bit off (e.g. because MIS_YAW_ERR is large), and it is better to track the actual setpoint.

Thomas Stastny de3ac12ecd fw pos ctrl params: clarify landing parameters, change defaults
FW_LND_USETER defaulted to 1 and FW_LND_ABORT terrain based bits all enabled. why? because using a distance sensor is critical to detecting when to flare, and we want to force the user to actively disable these safety settings if they so choose, so that they understand the implications.

Thomas Stastny 888e72661f fw pos ctrl: add option to fix the glide slope reference altitude
- new param, FW_LND_TER_REL

- flare is still triggered via the distance sensor, if enabled by FW_LND_USETERR

Thomas Stastny c60b215574 fw pos ctrl: allow negative landing glide slope relative altitude
when the vehicle did not track the slope well (e.g. at an offset above the track) and the altitude setpoint flattening on intersection with terrain, the throttle would spool up to smoothly intersect the newly flattened altitude setpoint, this could happen before the flare altitude was reached, which is bad. now the steady state glide behavior will be maintained, and flare can trigger at the appropriate time
