Thomas Watson 0ecdae05ba AP_Math: split radians into float and double variants 
Most `radians` uses give a float argument and use a float return type.
On `HAL_WITH_EKF_DOUBLE` boards this results in a bunch of unnecessary
conversions. Create separate double and float variants of the function
to eliminate the impact. The `DEG_TO_RAD` constant is already a float,
therefore there is no loss of precision in the operation.

We also need a variant that takes an `int` argument as these are
supplied in several places, primarily as constants, and the `int`
conversion is otherwise ambiguous.

Saves a few hundred bytes of flash on such boards.

 		9dc992619b AP_Math: prevent FPE in SITL when limiting accel vectors 
The cross-product code can produce something slightly negative. Fix
safe_sqrt to avoid barfing on that, as was originally intended, and
clarify why it's being used.

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
