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.

Mavlink: Get full sensor status even if only subset has changed when composing SYS_STATUS message (#11886)

* 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.

When using QGC and/or the Dronecode SDK it was possible to get in a
state where the two mavlink instances were both publishing their last
heartbeat_time and cause commander to consistently toggle between
data link lost and regained. With this fix, we only ever look at the
very last heartbeat time and therefore seem to avoid this issue.
