Renames and rescales the Copter and QuadPlane parameters that changed
name or units in 4.7 (attitude, position and waypoint controllers,
loiter, circle, RTL, land, pilot, rangefinder, MAV_ and stream rate
parameters), converts ARMING_CHECK to ARMING_SKIPCHK and moves the
MAVLink bits of SERIALn_OPTIONS into MAVn_OPTIONS. Files are converted
in place or into an output directory, --patch selects the 4.7.0 or 4.7.1
names and the vehicle is detected from the file content.
