Does: 1) updates the unit's homecity and the city it enters/leaves (the city's happiness varies). This also takes into account when the unit enters/leaves a fortress. 2) updates adjacent cities' unavailable tiles.
FIXME: Sometimes it is not necessary to send cities because the government doesn't care whether a unit is away or not.

Refresh the unit's vision.
This function has very small overhead and can be called any time effects may have changed the vision range of the unit.

Add hitpoints to the unit, hp_gain_coord returns the amount to add united nations will speed up the process by 2 hp's / turn, means helicopters will actually not lose hp's every turn if player have that wonder. Units which have moved don't gain hp, except the United Nations and helicopter effects still occur.
If 'game.server.killunhomed' is greater than 0, unhomed units lose 'game.server.killunhomed' hitpoints each turn, killing the unit at the end.

This is the basic unit versus unit combat routine. 1) A LOT of modifiers, bonuses etc are added to the 2 units' rates. 2) The combat loop, which continues until one of the units are dead or EFT_COMBAT_ROUNDS rounds have been fought. 3) The aftermath, the loser (and potentially the stack which is below it) might get wiped, and the winner gets a chance of gaining veteran status
Returns whether either side was completely powerless.

Creates a virtual unit, and sets its initial values, but does not register the unit in any other data structures or set the vision. If moves_left is less than zero, unit will get max moves; otherwise, it will get the specified number of movement fragments and will be considered moved. If hp_left is zero or less, unit will get full hp. homecity_id won't be set to units with "NoHome" flag. ptile must be a valid tile (its livability for the unit is not checked)
