This allows to bypass preflight and prearm checks.
During development there are regular cases where I just want to arm the
board/vehicle no matter what, and the preflight checks are guaranteed to
fail (e.g. sensors uncalibrated, inconsistent, powered via USB, etc.).
Allowing an easy and quick way to arm (assuming you know what you are
doing) helps to speed up development considerably and is less frustrating.
* This fix is necessary because usually uORB structs get initialized with
all zeros and then get filled with the fields that are actually in use.
* The number 0 for the mode slot was already commanding to switch to the
mode in slot one even though for example the joystick input via mavlink
does not use this mechanism at all.
This fixes the terrifying case where the drone disarms in-air just
because it receives a MAVLink disarm command. We now check param2 for a
magic number which enforces arming/disarming.
This is added to the mavlink protocol in:

AAs discussed in the devcall this functionality is only useful for
rotary-wing (multicopter) flying since it's a big safety hazard to
accidentally bring a fixed wing out of an auto mode e.g. a mission
and fly away in a straight line or into an obstacle.
outside the fence" to "engage geofence failsafe on transition". This
way, the pilot is not stucked in the non flight zone and can switch to
a manual mode and fly back or trigger RTL.
This commit adds Roll Pitch Yawrate Thrust (RPYrT) setpoint control to the
PX4 stack, enabling the UAV to follow specific yawrates sent from
offboard. It also introduces individual body_rate flags, along the
lines of mavros.
Tested on a MoCap enabled flight arena in KTH Royal Institute of
Technology, Stockholm. The MAV receives RPYrT setpoints from an
external PID controller to stabilize around position setpoints.
The UAV is also externally disturbed to assess the stability to
external unmodeled events.
Fixed Kabir comments.
Removed deprecated ignore_bodyrate.
Fixed integration test.
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.
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.
