e117bedf6a AP_NavEKF2: Adjust output observer tuning 
Use more accurate method by default.
Reduce overshoot on quaternion tracking

5c59922574 AP_NavEKF2: Fix bug that could publish bad compass offsets 
Magnetometer bias states will subject to larger errors early in flight before flight motion makes the offsets observable and the state variances reduce.
Adds a check on state variances.
Replaces the parameter check with a check of the actual filter fusion method being used.

165335b9e3 AP_NavEKF2: Improve ability to tune magnetic field learning 
Allow different process noise to be set for body (sensor bias) and earth field states.
This allows a stable magnetometer bias estimate to be available at end of flight whilst still allowing for external magnetic anomalies during landing.
Adjust default values to give stable mag bias learning and fast learning of external anomalies.

6523481c76 AP_NavEKF2: Improve tracking accuracy of output predictor 
Automatically use the highest gain consistent with a 5% overshoot to minimise RMS tracking errors.
Provide an alternative correction method for the position and velocity states that allows the user to specify the time-constant. This can be used to fine tune the output observer for for platform specific sensor errors and control loop sensitivity estimation noise.

fe06606193 AP_NavEKF2: Ensure corrected IMU data used by EKF 
Don't try to pop new IMU data from the buffer unless we have written data.
Correct IMU data as soon as it is popped from the buffer

1400dc9d02 AP_NavEKF2: Add tuning parameters for magentic yaw fusion

dc6836988c AP_NavEKF2: Improve ground based magnetic anomaly protection for copter 
The toilet bowling check during early flight has been removed. This check caused problems where bad compass calibration was the cause of the toilet bowling and resetting to the compass was a bad option. The handling of simultaneous failed mag and velocity innovations is already handled outside the EKF by the failsafe.
A check for yaw errors due to a ground based magnetic anomaly has been introduced.
The logic for in-flight yaw and magnetic field resets has been cleaned up and variable names improved.

e6f62080f5 AP_InertialSensor: fix best_diff on gyro initialization

best_diff[k] would be zero forever since diff_norm[k] >= 0 for any j.

d35cf60ce1 AP_HAL_Linux: I2CDevice: use read flag in read_registers_multiple

66f1ad9ed0 AP_HAL: Device: add support for read flag 
Many of our SPI and I2C sensors define the protocol of setting the most
significant bit of the register address in order to perform a read operation.
Thus, enable the use of a "read flag" that is ORed with the register's address.
Since this is an abstraction for general devices, it's a good idea to have zero
as the default value for that flag.

While at it, add documentation to read_registers().
