Update the speed of the vehicle.

It updates the cur_speed and subspeed variables depending on the state of the vehicle; in this case the current acceleration, minimum and maximum speeds of the vehicle. It returns the distance that that the vehicle can drive this tick. Vehicle::GetAdvanceDistance() determines the distance to drive before moving a step on the map.

Parameters

accel	The acceleration we would like to give this vehicle.
min_speed	The minimum speed here, in vehicle specific units.
max_speed	The maximum speed here, in vehicle specific units.

Returns: Distance to drive.
