Paul Riseborough fff2bd50f6 EKF: Fix bugs in position and velocity resets 
The position reset was not being compensated for velocity and measurement delay
The height was being reset with the position. It has been moved into a separate reset function
The maximum accepted GPS delay of 100msec was inadequate
The states  was being incorrectly reset to the GPS position and Baro height on initial alignment.

Paul Riseborough dbb8e12948 EKF: Add fusion method to constrain declination when unobservable 
When fusing 3-axis magnetometer data without absolute external aiding leg GPS), the declination is ultimately unobservable and the declination of the  field states and the vehicle heading will slowly drift over time. To prevent this we need to fuse in a declination to constraint the NE earth field estimates.

Paul Riseborough 2c8c6efb45 EKF: Eliminate use of power function to square numbers 
Use of the power function to square a number can be very inefficient depending on processor and compiler. Replace with an inlined function  that multiplies the number by itself. This has not been put into the maths library because the use of the sq() function is peculiar to the autocode generated for the EKF and an inlined function was desired.
