Paul Riseborough af3507ef3c AP_NavEKF2: Stop bad INS velocity spoiling height reset 
We should reset the velocity as well as the height if a reasonable reset value is available.

Paul Riseborough 97799ef0b3 AP_NavEKF2: Ensure that GPS origin is set before using data for height 2015-11-18 11:18:50 +11:00
Paul Riseborough b8427e5d95 AP_NavEKF2: Only allow rangefinder height option during optical flow nav 2015-11-18 11:18:50 +11:00
Paul Riseborough c9eea98142 AP_NavEKF2: Improve terrain height estimation 
The ad-hoc scaling of error growth has been replaced with a consistent method that uses the main nav filters published vertical velocity uncertainty and the terrain gradient assumption.

Paul Riseborough d820a538d5 AP_NavEKF2: Make magnetometer data available status global 
This assists with debugging and makes it consistent with other measurements that are buffered

Paul Riseborough 04228e0b3b AP_NavEKF2: Rework selection of height measurements for fusion 
GPS height has been added as a measurement option along with range finder and baro
Selection of the height measurement source has been moved into a separate function
Each height source is assigned its own measurement noise
If GPS or baro alt is not able to be used, it reverts to baro
When baro is not being used, an offset is continually calculated which enables a switch to baro without a height step.

Andrew Tridgell 75ea8f3dc0 AP_InertialSensor: removed "have sample" logic from drivers 
the frontend has all the information it needs, so we can simplify the
drivers some more

Andrew Tridgell 0e4bab74ba AP_InertialSensor: simplify sensor backends 
use common code for filtering and update, allowing each sensor driver
to be simpler and more consistent

Randy Mackay 36c0beb918 GPS_UBlox: reorder init to resolve compiler warning

Paul Riseborough 9b82b2200c AP_NavEKF2: Fix plane in-flight yaw reset 
The copter method was being used for plane and the plane method was not being run due to the change in flight status not being detected.
The plane reset method did not trigger if the EKF had already dragged the velocity states along with the GPS or could align to an incorrect heading.
The method has been reworked so that it resets to the GPS course, but only if there are inconsistent angles and large innovations.
To stop a failed magnetometer causing a loss of yaw reference later in flight, if all available sensors have been tried in flight and timed out, then no further magnetoemter data will be used

that could bring down the vehicle

Julien BERAUD 2f610a400a AP_HAL_Linux: fix perf

and check that perf is not NULL before indirection

Julien BERAUD f8f2833c88 AP_HAL_Linux: use I2C_SLAVE_FORCE in case of error 
When there is already a driver registered on an i2c bus, the I2C_SLAVE ioctl
returns an error.
When it happens, it is better to display a warning and try to force the address.
It is especially useful on the bebop when killing the regular autopilot that uses
iio drivers to access the imu because else we would need to manually unbind the
driver in an init procedure.

I have added a warning because this error can also be resulting of another cause.
If the error is not EBUSY, then panic

If the I2C_SLAVE_FORCE ioctl fails then we panic because one of the i2c devices
won't be working properly.

Andrew Tridgell cefb32566f GCS_MAVLink: fixed corner case in MAVLink routing 
when a GCS sends a command to a system ID that isn't our system ID,
the GCS may use a non-advertised component ID such as
MAV_COMP_ID_SYSTEM_CONTROL. Those packets should be fowarded to the
target system even though the target system has not specifically
advertised that target sysid/compid tuple.
