Andrew Tridgell 078eef91cb AC_WPNav: prevent I term buildup during landing
this prevents I term buildup in the XY velocity controller during
landing. This to account for the EKF giving a non-zero horizontal
velocity when we have touched down. The I term buildup in the XY
velocity controller can lead to the attitude error going above the
level for disabling the relax function as the throttle mix is
changed. That results in large motor outputs which can tip over the
vehicle after touchdown.

Thanks to Leonard for the suggestion

Randy Mackay cde2964f05 AC_WPNav: split set_speed_z into up and down
Also rely on AC_PosControl to store current target up and down speeds so wpnav's defaults are not affected by do-change-speed requests

Randy Mackay b0811c86e7 AC_WPNav: rename get_speed_xy to get_default_speed_xy
This hopefully clarifies that the default speed is returned and not the current speed
