It makes no sense to return 0 for the vector norm when the vector contains
NaNs. Just return NaN instead, Furthermore don't refuse to normalize vectors
when the length is small. Unless the length really is zero, it should be safe
to scale with the inverse length.

Unless all vector length are very close to unity, trying to avoid taking a
square root only slows things down (at least on x86_64 and Arduino Uno).

Fix use of abs() function with float argument.

The abs() function in stdlib.h takes an integer argument. Passing it a float
will silently convert the argument to int, and take the absolute value of the
result. Hence, abs(0.99) == 0, which is not what was intended. Use fabs instead.

The cross product is only defined for 3D vectors. Instead of checking the size
at runtime, only provide an implementation for N==3. Trying to use the cross
function with other vector sizes will then result in a link error.

Excessive parentheses only make the expressions hareder to read.

Replace use of float by double.

All values in a quaternion are declared double, let's not lose precision on
platforms where double is larger than float.
