* 8 kHz gyro, 4 kHz accel
* DLPF disabled
* scheduled using data ready interrupts
* FIFO is emptied at 1 kHz by default, but can adjusted via IMU_GYRO_RATEMAX from 250 Hz - 2000 kHz.
* On both px4_fmu-v4 and px4_fmu-v4pro the secondary IMU is an mpu9250 with the same driver
- checked register mechanism and simple watchdog
- driver checks for errors gradually and can reconfigure itself
- respect IMU_GYRO_RATEMAX at the driver level
- fixed sensor INT16_MIN and INT16_MAX handling (y & z axis are flipped before publishing)
- checked register mechanism and simple watchdog
- driver checks for errors gradually and can reconfigure itself
- respect IMU_GYRO_RATEMAX at the driver level
- fixed sensor INT16_MIN and INT16_MAX handling (y & z axis are flipped before publishing)
- increased sensor_gyro_fifo max size (enables running the driver much slower, but still transferring all raw data)
- PX4Accelerometer/PX4Gyroscope remove unnecessary memsets
* add support for unmanned underwater vehicles:
* airframe uuv_generic + uuv_hippocammpus including mav_type = 12 for submarines
* mixer for UUVs with X-shaped thruster setup similar to quadcopter
* add module uuv_att_control for underwater robot attitude control
* add rc.uuv_defaults/apps for autostarting e.g. ekf2 and uuv_att_control app
- 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)
- 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
* 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
This new airspeed module does:
-runns an airspeed validator for every airspeed sensor present, which checks measurement validity and estimates an airspeed scale
-selects another airspeed sensor if for the current one a failure is detected
-estimates airspeed with groundspeed-windspeed if no valid airspeed sensor is present
-outputs airspeed_validated topic

* The build is built with SPI4. At run time the signal GPIO_8266_GPIO2 it tested. If it is low the SPI4 is configured. If it is high SPI4 is not configured.
* board_common: Add Notion of Board has bus manifest
