Randy Mackay dd0d1d6b3c Copter: minor comment fixes to ekf failsafe 
the bad variances can be from the compass, velocity or position estimate

Randy Mackay 0f73d705a7 Copter: add failsafe_ekf_recheck 
this allows modes to retrigger the EKF failsafe if they move from a sub mode that did not require GPS to one that does

ArduCopter: Rework EKF failsafe

During flight operations it is the deviation in position of the vehicle that matters during most scenarios.
t patch ensures that an EKF fail-safe will be triggered when the position inconsistency exceeds check limits in addition to either a bad mag or velocity innovation.
This will stop velocity noise triggering an early fail-safe when electromagnetic interference is present.

Andrew Tridgell 1222aa2c43 Copter: make EKF mag variance check use max

Peter Barker e6c6189fe5 Copter: cope with change in namespace of LogEvent enum 
Also move Acro Trainer types into an enum class as the global defines
interfere with the Event names.

Also eliminate the Log_Write_Event wrappers.

Peter Barker 70d159cb38 Copter: raise EKF failure even if USB is connected 
This will let EKF go bad if your PixHawk is connected to your laptop.
This doesn't seem to be a problem for the other vehicles.

This also allows the EKF to go bad in-flight if you happen to have
connected (against AP's recommendations) your companion computer to your
flight controller via USB.  Since people do this, it is better to have
the checks than not.
