PX4 supports int32 parameter types by interpreting the 32 bits in
the float field as an int32 field. To signal this behaviour, it should
set the bit which is described as PARAM_ENCODE_BYTEWISE.
PX4 had always handled parameters this way but never actually sent the
capability (which back then was called PARAM_UNION), however, it should
have. This came up recently in the MAVLink devcall when these flags were
discussed. The takeaway was to remove the flags to make it clearer and
to make sure the projects (like PX4) send them out correctly.
mathlib: add second order reference model filter with optional rate feedback (#19246)
Reference models can be used as filters which exhibit a particular, chosen (reference) dynamic behavior. This PR implements a simple second order transfer function which can be used as such a reference model, additionally with rate feedback. The system is parameterized by explicitly set natural frequency and damping ratio. Another nice externality is that the output state and rate are kinematically consistent. Forward-euler and bilinear transform discretizations for the state space integration step are available.
- introduce BAT_AVRG_CURRENT param that is used for init of average current estimate
- increase filtering of average current estimation
- only update average current filter when armed

This fixes unspecified behaviour due to evaluation order of args.
It's up to the compiler whether next_number() or next_dots() is executed
first which means that the behaviour is not properly specified.
- sensor_baro.msg use SI (pressure in Pascals)
- update all barometer drivers to publish directly and remove PX4Barometer helper
- introduce baro cal (offset) mainly as a mechanism to adjust
relative priority
- commander: add simple baro cal that sets baro offsets to align with
GPS altitude (if available)
- create new sensors_status.msg to generalize sensor reporting
- things like arming requests can be dependent on current nav state
that might requested by a previous command, but the state machine
transition will only happen after command processing
