AC_PosControl: add xyz velocity controller
...
Velocity controller interpretsthe velocity requests as
desired velocities (i.e. feed forward). These are then used to update
the target position and also added to the target velocity.
Also renamed the set_desired_velocity() function to
set_desired_velocity_xy() to make clear only lat and lon axis are
updated.

AC_WPNav: reduce leash length for stopping
...
We now limit the target stopping point to 1x the xy leash length while
previously it was 2x. This is justified because this limit is only used
when the copter is travelling at higher speeds but at higher speeds air
drag tends to make the copter stop more quickly naturally.
