- fixes the deadlock in px4io ioctl mixer reset
- px4io Run() locks (CDev semaphore)
- mixer load goes through px4io ioctl MIXERIOCRESET which calls MixingOutput::resetMixerThreadSafe()
- MixingOutput::resetMixerThreadSafe() stores a Command::Type::resetMixer command in an atomic variable, schedules a work queue cycle, then sleep spins until the command is cleared
- the execution of the cycle eventually calls back into PX4IO::updateOutputs(), which tries to lock (and waits forever)
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
- new static notch filter configured via IMU_GYRO_NF1_FRQ and IMU_GYRO_NF1_BW
- existing notch parameters IMU_GYRO_NF_FREQ and IMU_GYRO_NF_BW become
IMU_GYRO_NF0_FRQ and IMU_GYRO_NF0_BW
