The EKF2 implementation uses one IMU per EKF2 core. When reporting the
gyro estimate, accel_ef estimate and gyro bias estimate we need to use
the values associated with the current IMU index being used by the
current EKF2 core. Otherwise we will have an inconsistency between the
gyro estimate and attitude estimate
This affects all multi-IMU systems using EKF2
this bypasses all attitude and position estimators and uses the SITL
state directly. It can be used for when the SITL backend cannot
provide perfect sensor data
This option now is passed when instantiating the code in ArduCopter, so
selecting the default value at compile time is not necessary anymore.
The motivation is to move vehicle specifc code out of the general
libraries. This patch shouldn't change behavior.
The AHRS_EKF_USE_ALWAYS define is used to force EKF to be always
used. It is defined only for building ArduCopter. Change it to be a
runtime flag. Keep its default value still based on the original define,
once the Copter uses it the define will be removed.

Fixes code that didn't take into account fall-through behaviour of C++ switch statements
Makes get_rigin furnction more generic allowing the consumer to decide what to do with an invalid origin
This patch adds additional methods to the the AHRS library so that the AP_InertialNav library dow nto have to access the EKF directly. This enables Copter to fly using the EKF nominated by AHRS_EKF_TYPE.
It will also pave the way to elimination of the AP_InertialNav library.
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.
This provides the calling vehicle software the abiity to request the EKF to not use GPS.
An integer is returned that indicates the type of operation available:
0 = request rejected (request will only be accepted if the EKF is in static mode, eg pre-armed)
1 = request accepted, attitude, vertical velocity and position estimates available
2 = request accepted, attitude, height rate, height, horizontal velocity and relative position estimates available
