- when either terrain data was temporarily not valid (flying at high
distance to the ground) or the vehicle was not close to the ground
(_param_ekf2_gnd_max_hgt) the ekf switched to using the land detector
ground effect flag.

- takeoff help is used for fixed wings, it increases the altitude setpoint
after a launch. A vtol does not need this as it's already sufficiently
high up in the air.

This reverts commit 4a71984f.

The noise for airspeed is now applied on the Gazebo side and we can
remove this hack.

the condition to enter the rc mode switch evaluation was neglecting
the first connection of an RC when "no RC switch changed". this means
depending on the actual initialization values of _last_sp_man and the
desired mode preselected on the RC while connecting it would not get
evaluated.

pure refactor using De Morgan's law to make the condition more intuitive
since you think about when should I enter and not when should I skip

pure refactor of the huge condition into smaller const bool junks

Auto mode traj - limit yaw setpoint rate of change when generated in the flight task instead of clamping the yaw rate in the controller

Move yaw setpoint slew rate from AutoLineSmoothVel to Auto. The slew rate is now applied consistently to all the auto FlightTasks

Add missing underscore prefix to a member variable in mavlink_main.cpp.h and delete unnecessary struct specifiers in mavlink_main.h.

Migrate an additional set of 16 variable initilializations from the Mavlink class constructor list to their respective declarations.

By declaring the params above the navigator modes inheriting from
mission block we make sure the params in navigator are set before
read in the constructor of mission block.

This prevents uninitialized padding from being written to dataman.

This variable was not set and lead to uninitialized memory being written
to dataman.

This should not be any functional change. The only difference are the
variable scopes, and early return versus nested ifs.

Inhibiting bias estimation using the EKF2_AID_MASK parameter only applies to the delta velocity bias states.

* Cherry pick the vehicle_imu PR #9756 src/modules/simulator directory work to submit as standalone PR.

* Modify the accelsim init method mag_report usage to match usage in measure() and mag_measure() methods in the class.

* Incorporate review comments in the accelsim.cpp init() method and also make the same modifications in gyrosim.cpp.

* Delete unneeded mag_report initialization from accelsim init() method.

* Deprecate unneeded measure() call from accelsim.cpp init() and gyrosim.cpp init().

When PX4FLOW is connected to PX4 through MAVLink (e.g., through a USB
port), the timestamp assigned to the distance_sensor was wrong. This fix
uses the same timestamp assigned to the optical_flow message created from
the same OPTICAL_FLOW_RAD MAVLink message.
