this increases the navigation precision of rovers using L1 control
down to the centimeter level

AP_L1_Control: Remove potential nan errors
...
If WP A and B were the same or ground speed was exactly zero, then the
previous code would produce a nan output. Protection against these
two cases has been added.
If WP A and B are equal, we track directly to the target waypoint

this makes the type much more obvious. Thanks to Tobias for the
suggestion.

AP_L1_Control: Addition of library for geometry calculations required for L1 Control.
...
1) Explicit control of tracking loop period and damping which removes previous
variation in period with speed and fixed damping ratio
2) Explicit control of track capture angle (now set to 45 degrees by default)
3) Removal of restriction on loiter radius being greater than L1 distance
The circle(loiter) control is a L1 and PD hybrid utilising L1 for waypoint capture and PD control for circle tracking.
