This allows external modes to individually check if they are flagged as
invalid/unresponsive.
Previously this was done only based on whether or not ArmingCheckRequest
was received, which does not work when multiple modes are running.
based on the message timestamp.
Previously it was possible to run into the following case:
- 2 external modes are registered (running inside the same ROS node)
- they time out due to the micro xrce agent being blocked for some reason
- PX4 removes them
- the latest arming check replies still arrive to PX4
- the application restarts
- the first mode gets registered
- PX4 handles the previous arming check reply, and clears
waiting_for_first_response, which reduces the timeout
- the second mode registers and as part of that checks for message
compatibility. This takes ~1s, triggering a timeout of the first mode
To separate accuracy requirements for VTOL hover and cruise.
- global_position_relaxed refers to having a valid horizontal velocity aid source
in the estimator and a set global reference position, but poses no requirements
on the accuracy of the provided position estimate.
- Auto flight modes Mission, Loiter and RTL, while in fixed-wing mode,
only require the relaxed global position going forward
- COM_POS_FS_EPH is thus no longer used on fixed-wing vehicles (resp. VTOL in FW)
- rename failsafe_flags.local_position_accuracy_low to failsafe_flags.position_accuracy_low

To make sure QGC also shows a box and reads out for "low battery"
and make events and mavlink_log reports consistent.
Low - Critical
Critical - Critical
Emergency - Emergency
We had a setup where the voltage was right at the threshold and the check
toggled continuously.
It still triggers immediately, and then keeps for 15 seconds
* add optical flow arming check
* removed deprecated mavlink_log_critical
* change SYS_HAS_NUM_OF description, keep max sensor at 1 since multiple instances are currently not support.
* restructure if/else blocks
A user configurable delay for the internal `vehicle_local_position` seems confusing in my eyes. It's a different timeout for fixed-wing and multirotor which might have made sense earlier but not really anymore since the topic is constantly published by the estimator and not expected to time out on either vehicle type and the parameter description is also misleading because it's outdated.
As the failsafe message can reference the health report, the health report
needs to be sent out first. This is generally the case, except there is a
rate limiter set to 2 seconds. So if the report changes quickly, it is
sent out delayed (potentially after the failsafe report).
Failing checks caused failsafe flags to stay true when enabling the circuit breaker but not rebooting.
Resetting the failsafe flags state when the circuit breaker is set resolves this issue.
