d948fcd72b fix control_allocator: check if 2. thrust and torque sp topic is valid 
Otherwise the 2. setpoint is equal to the first one. This is only an issue
if the 2. instance isn't advertised.

0074894637 control_allocator: disable backup schedule with lockstep 
The backup schedule triggers updates too early and leads to simulator errors:
ERROR [simulator] poll timeout 0, 22

20ccfbb719 control_allocator: remove failed motor from effectiveness 
- limit to handling only 1 motor failure
- Log which motor failures are handled
- Remove motor from effectiveness matrix without
  recomputing the scale / normalization

f4c3084c26 init adjustments to ensure used topics are advertised early (primarily for logging) 
- multi-EKF create each instance as soon as IMU & mag are advertised (before device id populated)

960003a86a control_allocator: fix weak authority matrix check & update

c51dc3b4b7 ControlAllocator: Set all the elements of a row to 0 if that row has weak authority 
Weak authority on a axis is currently defined as: none of the actuators have an
effectivness on this particular axis larger than 0.05.

df0e402c44 CA: refactor logic for matrix updating 
-pass flag EffectivenessUpdateReason into effectiveness, indicating if there was an external
update or not. Reasons for external updates are:
  -config changes (parameter)
  -motor failure detected or certain redundant motors are switched off to save energy

0950bb81ab ControlAllocation: update normalization scale only if matrix updated is forced 
The forced flag is used to distinguish between updates due to a configuration
(parameter) change (only enabled when disarmed), and matrix updates due to motor
tilt change. Only update the normalization scale if the forced flag is true, and
use a tilt angle of vertical position for it to have the scales tilt-invariant.

5259877b1b control_allocator: update matrix normalization 
- only normalize rpy for MC matrices
- for thrust use the 3D vector, so it works for FW and tilt rotors as well

This keeps MC unchanged.

70e46a194f control_allocator: major refactoring & additions 
- allow effectiveness matrix to select control allocator method
  (desaturation algorithm)
- add actuator_servos publication
- add support for multiple matrices (for vtol)
- add updateSetpoint callback method to actuator effectiveness to allow it
  to manipulate the actuator setpoint after allocation
- handle motor stopping & reversal
- add control surfaces & tilt servos
- handle standard vtol + tiltrotor
- rename MC rotors params & class to be more generically usable
- fixes and enables ActuatorEffectivenessRotorsTest
