Peter Barker 560f17a570 AP_NavEKF3: use union to alias array and struct access to states 
This avoids creating two pointers of different types to the same memory.

Having two pointers to the same memory can lead to the compiler
optimising code such that a write to one pointer is rearranged to be
either before or after a read from the other pointer depending on
which is deemed faster - not a good outcome.

Peter Barker b68a91d171 AP_NavEKF3: remove default clause in setAidingMode 
All aiding modes should be covered in the switch statement; adding the
default clause squelches a potentially useful compiler warning

Andrew Tridgell c13eaf0c7f AP_NavEKF3: removed create() method for objects 
See discussion here:

  https://github.com/ArduPilot/ardupilot/issues/7331

we were getting some uninitialised variables. While it only showed up in
AP_SbusOut, it means we can't be sure it won't happen on other objects,
so safest to remove the approach

Thanks to assistance from Lucas, Peter and Francisco
