PR #12681 added a check to the MulticopterLandDetector::_get_maybe_landed_state() method for a valid vehicle_attitude.timstamp value to finish work in PR #9756. It was discovered that the addition of that check leaves it possible to fly in acro mode without a valid attitude and auto-disarm can engage, allowing the multicopter to fall out of the sky.
* 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
-moved rc.mavlink to the boards optional rc additions (now it's called rc.board_mavlink) to handle board specific mavlink needs (mavlink over usb, ethernet, additional streams, etc.)
-mavlink module will be responsible to usb defaults, therefore less args are needed to be passed to mavlink module if one wants to use mavlink over usb.
-the way to check if connection is usb is by it's designated variable and not by config mode.

This fixes the regression where we saw this in SITL:
ERROR [mavlink] system boot did not complete in 20 seconds
The reason was that the stream subscription requests were not checked
because the while loop was not running yet because mavlink was not
booted completely.
By moving the stream subscription requests into a function we can run
them even if we don't run the rest of the loop.
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.
part to avoid having to scale its saturation separately. This is
required to avoid premature saturation of the integrator when using
the K term.
Also remove double saturation of the integrator
A NAN is interpreted in the FlightTaskAuto as a non-valid global coordinate and sets a local position.
If a zero is sent instead, the global coordinate is recognized as valid and will be executed.
This is a problem when the global position is gained for the first time after takeoff and that a valid global reference did not exist before
* ekf2: Move handling of invalid range finder data inside ecl library
The ecl library EKF is able to use vehicle motion and in-air status to better determine when the default on-ground range finder reading can be used.
The description for the EKF2_MIN_RNG parameter has been updated to make its use clearer.
After landing it can happen that a second take off is detected and then the _takeoff_time is rest, resulting in a wrong total flight time counter. With this fix the flight time is reliably counted from the first take off until the vehicle is disarmed. Normally the vehicle will not spend much time armed after landing, if it does the flight time will be off but this is the same as before this fix. This fix was tested in several flight experiments.
