Andrew Tridgell 4e6f0c0ef4 AP_NavEKF: getYawData also provides number of clipping models 
In the case of the compass calibrator we do not want to use the GSF
result if any model is degenerate.  We've had a compass calibrate in
flight 180-degrees out from what it should have.

Paul Riseborough afb31bc4f5 AP_NavEKF: Add underflow protection to yaw GSF weight normalisation 
This improves protection against a condition where if all yaw hypothesis filers have very large innovations, the weights of Gaussian densities can underflow leading to failure of the weights to converge.

Andrew Tridgell 4fdbbd8984 AP_NavEKF: added functions to see if a nav source is enabled 
this allows us to avoid initialising ring buffers when not needed

Andrew Tridgell ab917ed92e AP_NavEKF: add more protections on ring buffer code

initialised

Peter Barker fdbffd19c6 AP_NavEKF_Source: remove defaults for baro and compass 
This makes all our defaults "NONE", meaning that a user will not see a
prearm failure for any source other than those in the primary set when
using the default configuration.

Paul Riseborough 4a743a3827 AP_NavEKF: Remove unnecessary reset operations and class variables 
The setting of EKF state variances is only required when commencing or recommencing velocity fusion.
The function that resets the EKF and GSF class variables has been renamed to be more consistent with its function.
