This was only handled outside because FlightTaks lived in the
multicopter position controller which produces the data that was
needed but now it doesn't make sense anymore to handle this
subscription separately.
It's better to have it inside the base task to have the data available
on task activation sucht that e.g. Altitude mode can take over smoothly
from Position mode.
For any normal use case where a downwards velocity setpoint is set
this works exactly the same as before.
E.g. autonomous landing, landing in Altitude or Position mode
The advantage is that the very common case where a vehicle tries
to hold a constant altitude but fails to do so e.g. during a hard brake
with too much lift the resulting downwards velocity was interpreted
as descend intent and since the vehicle already struggled to hold altitude
with low thrust and was not moving fast anymore because it was braking
this lead to a lot more false positives on certain vehicle types.
The disadvantage is that not setting a downwards velocity setpoint but
just moving the position setpoint into the ground does not result in
land detection anymore. We do not use this method of landing anymore for
quite a while. It's not recommended and I wonder if there's some rare use
case like offboard where this is done.
We could add an additional case for the specific case to land with a
position setpoint only.
The tree stages used arbitrary 350, 250 300ms totally 900ms
So this changes it to each stage to a third of the parameter.
Default it is 1 second -> 333ms per stage.
Script failed for me with following error
PX4-Autopilot/Tools/setup/arch.sh: line 159: syntax error near unexpected token `else'
PX4-Autopilot/Tools/setup/arch.sh: line 159: ` else'
Seems like there is nothing to do in case of positive if case.
Changed code should maintain logic
It was used to make the vehicle needing to accept the waypoint after a VTOL transition in the new VTOL mode

If the GPS data is passed from companion computer, there may be inaccuracies
with timesync. This may cause time deltas to overflow.
Make the time delta calculation using floats directly, wich results in negative
numbers in case there are such inaccuracies.

Instead of only keeping track of the sequence ID of specific "supported"
components, we now keep track of any sysid/compid of an incoming
message. Before this change, unknown components (such as jMAVSim) would
completely screw up the mavlink message stats and create confusion (at
least in my case).
With this change we currently keep track of up to 8 other components.
Once we reach the limit, we will print a warning.
Without these fields the pre-arm check would complain and fail.
Also, the voltage is adjusted to be at around 70% rather than 30% which
would almost start to trigger warnings.

based on our experience with VTOL it makes sense to change the yaw mode default. You always want your VTOL to yaw in transition direction before starting the transition.
