300195ff18 AHRS: A few small changes
1) Moved the criteria for using GPS to defines in anticipation of moving into
AHRSSettings
2) Only use the mags for updates if the vector length is within 20% of nominal
to avoid updating when it's nonsense
3) Reinitialize position when swapping between indoor and outdoor
4) Dont use mags for first 5 seconds after initialization, sometimes seems to
cause issues
5) Dont use mags until magnetic field at your location is set and a magnetic
field is loaded
6) Dont use GPS if home location hasnt been set

indoor or outdoor as well as if you use a mag indoor (if you do set the z
variance higher than it calibrates to).

Flight: Create PositionDesired (the active waypoint) UAVObject and make the FlightSituationActual no update since it not used.

UAVObjects/PositionActual: Remove unused GPS fields
UAVObjects/PositionActual VelocityActual: Split the velocity into a separate object.  ALso make sure all the information telemetered around is in cm to avoid using floats.
UAVObject/GuidanceSettings: New guidance settings object for the guidance module
Flight/Posix: Add the new objects to the Posix sim
Flight/Guidance: Computes a desired velocity based on position error than runs a PID loop to control roll and pitch to achieve that velocity.  All distances are in cm, and updated the PositionActual fields to reflect this and use int32.

9b28f2d72c OP-167 OP-157 AHRS/Calibration: Added mag scale and really cleaned up calibration.
Calibration should take less time now too (using second moments to estimate
variance in one pass).  Now need to change to multiple messages to get the
calibration in to keep the request message size minimal.  Also currently
running sensor calibrate doesn't store the gyro bias so if you want to use this
you'll have to tweak it manually.  I'll fix that step tomorrow.

cdb8aa37a0 ahrs: Only read mag data when it has been updated
The AHRS mainloop was reading the mag data on every
loop regardless of whether new data was actually
available.  Now that the MAG_DRDY signal is monitored,
we can read only at the rate (10Hz) new data is actually
produced by the sensor.

This also enables future improvements that will remove the
filtering work that is still being done on the mag data on
every iteration.
