331cb21dee manual_control_setpoint: change stick axes naming
In review it was requested to have a different name for
manual_control_setpoint.z because of the adjusted range.

I started to investigate what naming is most intuitive and found
that most people recognize the stick axes as roll, pitch, yaw, throttle.
It comes at no surprise because other autopilots
and APIs seem to share this convention.

While changing the code I realized that even within the code base
the axes are usually assigned to a variable with that name or
have comments next to the assignment clarifying the axes
using these names.

83246c84cf Switch manual_control_setpoint.z scaling from [0,1] to [-1,1]
To be consistent with all other axes of stick input and avoid future
rescaling confusion.

Note: for the MAVLink message 69 MANUAL_CONTROL it's using the full range
according to the message specs now [-1000,1000].

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

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

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.

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).

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.
