Render positive movement points as text, including fractional movement points, scaled by SINGLE_MOVE. Returns a pointer to a static buffer. 'reduce' is whether fractional movement points should be reduced to lowest terms (this might be confusing in some cases). 'prefix' is a string put in front of all numeric output. 'none' is the string to display in place of the integer part if no movement points (or NULL to just say 0). 'align' controls whether this is for a fixed-width table, in which case padding spaces will be included to make all such strings line up when right-aligned.

Returns whether the unit can move from its current tile to the destination tile. An enumerated value is returned indication the error or success status.
The unit can move if: 1) The unit is idle or on server goto. 2) Unit is not prohibited from moving by scenario 3) Unit is not a "random movement only" one, or this is random movement 4) The target location is next to the unit. 5) There are no non-allied units on the target tile. 6) Animals cannot move out from home terrains 7) Unit can move to a tile where it can't survive on its own if there is free transport capacity. 8) There are no peaceful but non-allied units on the target tile. 9) There is not a non-allied city on the target tile when enter_enemy_city is false. When enter_enemy_city is true a non peaceful city is also accepted. 10) There is no non-allied unit blocking (zoc) [or igzoc is true]. 11) Triremes cannot move out of sight from land. 12) It is not the territory of a player we are at peace with, or it's terrain where borders don't count 13) The unit is unable to disembark from current transporter. 14) The unit is making a non-native move (e.g. lack of road)

This function calculates the movement cost to unknown tiles. The base value is equal to the highest movement cost the unit can encounter. If the unit cannot enter all terrains, a malus is applied. The returned value is usually cached into utype->unknown_move_cost and used in the path-finding module.
