Checking the first output_limited for a disarmed value is fragile.
For example a disarmed value might be within the range of min/max output
values and could then be triggered while armed.
The documentation of the thrust model parameter `THR_MDL_FAC` did not
mention both thrust and "PWM" being relative values. Also the use of the
term PWM could be misleading, since the model is applicable to CAN ESCs
as well.
This commit rephrases the user documentation string and a few source
code comments, but no logic changes are made.
ClosesPX4/Firmware#13105
* adds a work_queue systemcmd that will bring a tree view of all active work queues and work items
* WorkQueues now track attached WorkItems and will shutdown when the last WorkItem is detached
added and using circuit_breaker_enabled_by_val() where possible instead of circuit_breaker_enabled() which search for cbrk parameters by name, which is extensive process.
