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
- this provides some extra space when the FIFO transfers don't align perfectly
- I've also made an effort to keep the different drivers (icm20602, icm20608g, ism330ldc) in sync so we can factor out the common portions later once we've confident in the pattern.
* Treat UAVS diffrently from manned aviation
* Added fake_traffic testing functionality,
* Added NAV_TRAFF_AVOID Hold and Landmode
* Added Behavior: HOLD Position to collision avoidance mode and implemented Landmode to collision avoidance.
Boards where no Hardware GUID is defined will send 0 as GUID.
Right now collision avoidance for more than one FMU without Hardware GUID is not possible.
We should consider adding a randomly generated HW GUID as a placeholder for legacy Boards
We now check individually for empy and genmsg.
Also, my recommendation is to use pip3 as a user to install the
dependencies as this is least intrusive and should work on all
platforms.
* parameter and logic to commander for triggering failsafe from external automatic trigger system.
* logic to startup script for enabling ATS. Added uORB publishing to pwm_input module.
* Refactored out CDev usage from pwm_input and ll40ls. Refactored out ll40ls specifics from pwm_input and cleaned up dead code.
- rename of flag in position sp: from allow_weather_vane to disable_weather_vane
- flag now doesn't have to be set for all auto modes, meaning that weather vane is also active outside of mission
- flag is set before front transition to align with wp, and unset after alignment is over

- uses the FIFO and SPI DMA to transfer full raw data (8 kHz gyro, 4 kHz accel)
- new sensor messages for better visibility
- sensor_{accel, gyro}_fifo: full raw data for optional logging and analysis
- sensor_{accel, gyro}_status: metadata, clipping, etc
- currently not enabled by default

* FW attitude controller, FW position controller and VTOL attitude controller subscribe to airspeed_validated topic
* add possibility to switch off the airspeed valid checks
* remove airspeed valid checks from commander
* clean up of VTOL transition logic
* Airspeed Selector: remove dynamic allocation of airspeed validators (depending on number of connected sensors) but do it statically for the maximum number allowed. Check for number of connected sensors not only during start up, but always when vehicle is disarmed.
* Airspeed Selector: change work queue from lp to att_pos_ctrl as this module is safety-critical
* add airspeed selector to px4_fmu-v2 defaults
