AP_InertialSensor: check range of accels in 3D calibration
...
during 3D accel cal it is possible to get data which passes the sphere
fit but which has very poor coverage and does not provide sufficient
data for a good result. This checks that each axis covers a range of
at least 12 m/s/s in body frame

AP_InertialSensor: added INS_CALSENSFRAME parameter
...
this allows us to detect if accel calibration was done in sensor frame
or not. If it was done in sensor frame then the accel calibration is
independent of AHRS_ORIENTATION, which makes it easier to move a board
to a new airframe without having to recalibrate.

AP_InertialSensor: use accelerometers to prevent bad gyro cal

if the board is rotating at a steady rate we can end up with a bad
gyro calibration. This can happen on a steadily moving platform such
as a ship.
This uses the accelerometers to detect the steady movement and not
accept the gyro calibration

AP_InertialSensor: make calibrated() function fast enough to call in flight
...
this will be used in plane to make AHRS SYS_STATUS unhealthy if a user
tries to fly with EKF enabled without a full 3D accel cal.
Note that it doesn't rely on using AP_Param load() to detect that a
value has been set, as some users are first doing a 3D cal then later
doing a 1D cal. In that case load() was returning true and would give
a false positive
