- remove all remaining IOCTLs for accel and gyro and handle all calibration entirely in sensors module with parameters
- sensor_accel and sensor_gyro are now always raw sensor data
- calibration procedures no longer need to first clear existing values before starting
- temperature calibration (TC) remove all scale (SCL) parameters
- gyro and baro scale are completely unused
- regular accel calibration scale can be used (CAL_ACC*_xSCALE) instead of TC scale
Greatly improves the noise on the d-term on a Kopis 2. Apparently the order
of filtering vs differentiating matters.
Also disables the DGYRO filter by default, as the D-term now already has
a default filter of 30Hz applied.
- IMU integration move from drivers (PX4Accelerometer/PX4Gyroscope) to sensors/vehicle_imu
- sensors: voted_sensors_update now consumes vehicle_imu
- delete sensor_accel_integrated, sensor_gyro_integrated
- merge sensor_accel_status/sensor_gyro_status into vehicle_imu_status
- sensors status output minor improvements (ordering, whitespace, show selected sensor device id and instance)
I've added a queue depth of 4 for sensor_accel and sensor_gyro. This is initially added because it's not always possible for the `vehicle_acceleration` to keep up with every publication of the primary accelerator as it runs in the same thread as ekf2, various controllers, etc.
Later this mechanism will be used in a few areas
- rate limit `vehicle_angular_velocity` and `vehicle_acceleration` without missing any raw data
- move IMU integration to `vehicle_imu` and out of the actual driver threads, eliminating the need for sensor_accel_integrated and sensor_gyro_integrated
- integrate raw gyro synchronized with optical flow measurements
- introduces parameter IMU_DGYRO_CUTOFF to configure the angular acceleration low pass filter
- the angular acceleration is computed by differentiating angular velocity after the notch filter (IMU_GYRO_NF_FREQ & IMU_GYRO_NF_BW) is applied

- gyro filtering (low-pass and notch) only performed on primary gyro in `sensors/vehicle_angular_velocity` instead of every gyro in `PX4Gyroscope`
- sample rate is calculated from actual updates (the fixed value was slightly wrong in many cases, and very wrong in a few)
- In the FIFO case the array is now averaged and published in `sensor_gyro` for filtering downstream. I'll update this in the future to use the full FIFO array (if available), but right now it should be fine.
- this is a new module for temperature compensation that consolidates the functionality previously handled in the sensors module (calculating runtime thermal corrections) and the events module (online thermal calibration)
- by collecting this functionality into a single module we can optionally disable it on systems where it's not used and save some flash (if disabled at build time) or memory (disabled at run time)
- split out integrated data into new standalone messages (sensor_accel_integrated and sensor_gyro_integrated)
- publish sensor_gyro at full rate and remove sensor_gyro_control
- limit sensor status publications to 10 Hz
- remove unused accel/gyro raw ADC fields
- add device IDs to sensor_bias and sensor_correction
- vehicle_angular_velocity/vehicle_acceleration: check device ids before using bias and corrections
and remove the px4_ prefix, except for px4_config.h.

Transitional headers for submodules are added (px4_{defines,log,time}.h)
Some of these perf counters were useful during initial development, but realistically aren't needed anymore, some are redundant when we can now see the average interval from `work_queue status` and some of them simply aren't worth the cost at higher rates.
* 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
