game_remove_unit() calls unit_list_unlink() twice even 
for homeless units (unlink from map, and from player.units)

(The line numbers seemed too strange to tell which was
being called.)

I was able to re-produce this situation: on the first turn, before
moving a settler or building a city, an explorer gets killed by
barbarians in a hut.  But I didn't get a segfault.  :-(
