Load all items from the look-ahead queue into the trapezoid velocity

Once a hop is performed, it will only be re-issued if the z-axis has been
moved in the meantime. Usually it is only moved by a z-homing so doing so
will cause safe_z_home to do the hop on the next homing action.
When z-axis is homed, x and y positions are known. When setting this
boolean option, these are set back to their last positions.
Whenever a hop is specified it is re-issued after the Z axis has been
homed. This is especially necessary when a pressure-based probe is used.
Also, the module decides if a hop is necessary, based on either a known
Z position or a flag that is set whenever the motors are disabled.
