AP_NavEKF2: rework yaw and magnetic heading reset logic
...
Splits in-flight yaw alignment completed status into separate yaw and magnetic field flags.
Reduce the number of places where decisions to perform a yaw and field reset are made.
Don't perform a reset unless there is is data in the buffer
Don't use 3-axis fusion if the field states still need to be reset.
When starting 3-axis fusion request a reset if not previously performed.
Ensure magnetometer and GPs heading resets are alwasy perfomred with data at teh correct time horizon.

The commencement of airspeed fusion could cause pitch errors due to small variances and large innovations. This issue is addressed by the following changes:
1) The airspeed measurement is used to set wind states to a value that reduces initial innovations.
2) The wind state variances are set to values that better reflect the wind speed uncertainty

- Change the order of the icosahedron triangles so that there's a uniform way of
finding the opposite triangle. The order visually still makes sense.
- Change test to accommodate the order change.

AP_HAL_SITL: pass signed value to abs()
...
Passing an unsigned value to abs() causes compilation error in gcc 6.1.1
(and doing that doesn't make sense too).
As a bonus, this patch fixes the code, since, for two unsigned integers
a and b, such that a > b, (a - b) without the casting to a signed
integer would produce garbage in the context of this patch. The type
int32_t is enough for the cases covered by this patch.

Instead of a couple seconds, make it about 15sec. This makes TECS happy by not glitching the height demand as much. When applied too fast the TECS height demand causes a large single oscillation as it chases the filter lag.
