Andrew Tridgell f7e138bddd AP_NavEKF2: use parent class for intermediate static variables
this makes the code faster as well as using less memory when both EK2
and EK3 are enabled

Peter Barker 952d4d2cbc AP_NavEKF2: initialise Kfusion stack variable to fix compilation
This fixes the compilation, as previous patches have done.

Andrew Tridgell 255981c60c AP_NavEKF2: moved some of the intermediate vars to the stack
this keeps stack frames below 1k, while giving faster access to the
variables and saving more memory

priseborough a8f3a374e2 AP_NavEKF2: replace sqrt function calls with sqrtf
Prevents compiler errors and un-wanted use of double precision types

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 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 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.

Paul Riseborough ddb7d92fc8 AP_NavEKF2: Fix timing jitter in airspeed fusion
The airspeed observation buffer was only being checked when new data arrived instead of every frame which introduced some timing jitter. The buffer is now checked every filer update step.
The duplication and inconsistent naming of booleans used to indicate availability f data has been fixed.

Siddharth Bharat Purohit b3c8dcee34 AP_NavEKF2: measurement buffer refactor 2015-11-23 19:34:50 +11:00
Paul Riseborough f9cadaf15c AP_NavEKF2: Increase resolution of innovation consistency gate parameters
Also adds protection against setting the gate to a number that would casue numerical errors.

Paul Riseborough 577670ccee AP_NavEKF2: Reduce memory required by 6KB when running at 400Hz
Down-sample the IMU and output observer state data to 100Hz for storage in the buffer.
This reduces storage requirements for Copter by 75% or 6KB
It does not affect memory required by plane which already uses short buffers due to its 50Hz execution rate.
This means that the EKF filter operations operate at a maximum rate of 100Hz.
The output observer continues to operate at 400Hz and coning and sculling corrections are applied during the down-sampling so there is no loss of accuracy.

Paul Riseborough 74da4d8e57 AP_NavEKF2: Remove GPS glitch offset logic
Correction for steps in position and velocity caused by resets following GPS glitches and other events are now handled by the control loops.

Paul Riseborough 8526a8ba7e AP_NavEKF2: Level processor loading between frames
Don't fuse other measurements on the same frame that magnetometer measurements arrive if running at a high frame rate as there will be insufficient time to complete other operations.
