[nav] exceeding_time on segment

Add an 'exceeding_time' attribute to 'go' and 'path' blocks that tells how
many seconds the plane should fly after the end of the segment before
completing it.
It is equivalent to giving a negative 'approaching_time' (and these two
attributes are of course not compatible with each other).
In addition some math functions in nav are forced to float.
