Wipe orders when ship, plane, land unit or nuke changes owner

Browse source 
Use new unit_wipe_orders() for violent takeover (takeover_unit() on
behalf of assault, attack, board, lboard, paradrop and pboard), and
peaceful takeover (unit_give_away() on behalf of arm, disarm, load,
unload, lload, lunload, scrap, scuttle, tend, trade).

Before, takeover_unit() cleared only group, mission and ship retreat
orders, and unit_give_away() only group and mission.  Orders that
weren't cleared:

* Mission op area (visible in xdump)

* Ship autonav orders

* Ship sail path including ship to follow and mobility quota

* Plane range limit

* Land unit retreat orders and retreat percentage
