Peter Barker dc62483e0c AP_Math: move zeroing to header, use memset, reuse in identity 
this method is in ITCM memory on STM32 - which makes small optimisations worthwhile

Peter Barker d7caf1e6b5 AP_Math: remove method operator 
remove the metho operator from the class.

This means this will no longer work:

Quaternion q{0,1,2,3};
q(5,6,7,8);

.... that used to set the quaternion componets, but is an odd / atypical syntax to use

Peter Barker 8df2d4998b AP_Math: improve gating of use of AP_InternalError library 
- gate calls into library directly on the define
 - INTERNAL_ERROR becomes empty if library not compiled in

Andrew Tridgell e97f5d8012 AP_Math: mark test_math_double.cpp as double precision source 
fixed test_math_double
the wrap check needs to be wrap_PI() as otherwise rounding of 2*PI if
just over 6.28 will give a large error
ensure double tests are double
