Andrew Tridgell 239c18792a AP_AHRS: fixed dead-reckoning groundspeed vector
this is essential for RTL in planes on GPS loss

Andrew Tridgell 5b0b9ef962 AP_AHRS: don't do yaw correction in DCM while calibrating compass
this avoids applying bad compass yaw, and helps the compass
calibration code

Andrew Tridgell 1f9a3dd1bd AP_AHRS: improved init attitdue in DCM
this tries harder to get a good IMU sample for the initial attitude
estimate. I have seen cases of bad IMU data on startup and this makes it
much less likely

Peter Barker 4ed7fb154f AP_AHRS: supply missing get_relative_position_D_home
Simply returns the baro altitude (like EKF does if it lacks
position)

Mathieu OTHACEHE 152edf7189 Global: remove mode line from headers
Using a global .dir-locals.el file is a better alternative than
reincluding the same emacs header in every file of the project.

dgrat 6d3b491c02 AP_Math: Replace is_equal with a type safe template function
It makes sense to consider also other floating point types.

dgrat 41661f815f AP_Math: Replace the pythagorous* functions with a variadic template
The new function can deal with a variable number of function parameters.
Additionally, I renamed the functions to norm(), because this is the
standard name used in several other projects.

Lucas De Marchi da86e29c27 AP_AHRS: remove check for AVR CPUs
Remove the checks for HAL_CPU_CLASS > HAL_CPU_CLASS_16 and
HAL_CPU_CLASS >= HAL_CPU_CLASS_75. Corresponding dead code will be
removed on separate commits.

Gustavo Jose de Sousa 84f811fe76 AP_AHRS: use compass get_{field,offsets}() functions
Both functions are equivalent, so we're going to simply use
get_{field,offsets}() instead of get_{field,offsets}_milligauss().

Gustavo Jose de Sousa 54d5277842 AP_AHRS: standardize inclusion of libaries headers
This commit changes the way libraries headers are included in source files:

 - If the header is in the same directory the source belongs to, so the
 notation '#include ""' is used with the path relative to the directory
 containing the source.

 - If the header is outside the directory containing the source, then we use
 the notation '#include <>' with the path relative to libraries folder.

Some of the advantages of such approach:

 - Only one search path for libraries headers.

 - OSs like Windows may have a better lookup time.

Andrew Tridgell 9c776736c1 AP_AHRS: use delta_velocity and delta_angle in DCM
this prevents an aliasing effect by using the correct delta velocity
time value for each accelerometer sample used

Andrew Tridgell 3529e02675 AP_AHRS: if we have 3 gyros then only use first two
the 3rd gyro on a PH2 has a lot more noise as it is not vibration

Andrew Tridgell 4ad643b233 AP_AHRS: use a common function for updating the CD values

Andrew Tridgell 63c06ea2af AP_AHRS: fixed calls to DCM in parent class
use_compass() and reset() are common to AP_AHRS_DCM and
AP_AHRS_NavEKF. As AP_AHRS_NavEKF is a child of AP_AHRS_DCM, when we
call use_compass() from within AP_AHRS_DCM we actually end up calling
AP_AHRS_NavEKF::use_compass().

This has the effect of disabling the compass in DCM when EKF is active
and EKF has decided not to use the compass. That means that the DCM
yaw (and in fact the whole attitude) can get badly off while EKF is
enabled, making DCM an ineffective fallback if EKF fails.

The fix is to call the specific class versions of use_compass() and
reset()
