Lucas De Marchi 180359d6dd AP_Math: fix unit test
For ROTATION_ROLL_90_PITCH_68_YAW_293 consider the angles as 90, 68.8
and 293.3 degrees to pre-calculate rotation. This matches the rotation
matrix used in code.

While at it, check not only the values are close enough but also the
length of the vector.

Lucas De Marchi ba3325ffd3 AP_Math: rename rotation
The rotations are supposed to follow the name of the enum, in order. The
ROTATION_YAW_293_PITCH_68_ROLL_90 was added with the name of an
intrinsic 321 rotation, but the matrix is actually a 123 rotation,
following the other rotations already present.

Change the name to follow the other names.

Lucas De Marchi e0a0514c79 AP_Math: turn MIN/MAX macros into inline functions
The problem with the current MIN/MAX macros is that they evaluate twice
the arguments. For example, these cases provide unintended results:

	// a is incremented twice
	a = MIN(a++, b);
	// foo() with side-effects
	a = MIN(foo(), b);

The alternative implementation here was provided by Daniel Frenzel using
template function. It doesn't have type safety as std::min and std::max,
but adding type safety would mean to check case by case what would be a
reasonable type and add proper casts. Here the arguments for MIN and MAX
can have different types and the return type is deduced from the
expression in the function.

Inspecting the current callers no place was found with the unintended
results above, but some in which now we don't calculate twice the
parameters will benefit from this new version. Examples:

	float velocity_max = MIN(_pos_control.get_speed_xy(), safe_sqrt(0.5f*_pos_control.get_accel_xy()*_radius));

	float acro_level_mix = constrain_float(1-MAX(MAX(abs(roll_in), abs(pitch_in)), abs(yaw_in))/4500.0, 0, 1)*ahrs.cos_pitch()

	accel_x_cmss = (GRAVITY_MSS * 100) * (-(_ahrs.cos_yaw() * _ahrs.sin_pitch() / MAX(_ahrs.cos_pitch(),0.5f)) - _ahrs.sin_yaw() * _ahrs.sin_roll() / MAX(_ahrs.cos_roll(),0.5f));

	track_leash_slack = MIN(_track_leash_length*(leash_z-track_error_z)/leash_z, _track_leash_length*(leash_xy-track_error_xy)/leash_xy);

	RC_Channel_aux::move_servo(RC_Channel_aux::k_sprayer_pump, MIN(MAX(ground_speed * _pump_pct_1ms, 100 *_pump_min_pct),10000),0,10000);

Lucas De Marchi 2591261af6 Global: rename min and max macros to uppercase
The problem with using min() and max() is that they conflict with some
C++ headers. Name the macros in uppercase instead. We may go case by
case later converting them to be typesafe.

Lucas De Marchi 5244559010 Minimize AP_Progmem.h includes
Most of AP_Progmem is already gone so we can stop including it in most
of the places. The only places that need it are the ones using
pgm_read_*() APIs.

In some cases the header needed to be added in the .cpp since it was
removed from the .h to reduce scope. In those cases the headers were
also reordered.
